freebeer (2018-02-04 11:53:20+00:00): Hi Mike,
Sorry for the delay in my reply.  I had one of the regular cullings that loses all my bookmarked pages of interest, so I'm hoping I can find them all from Pascal's helpful website.
You will find that OpenStreetMap develops in stages, all different.  For example, you have opened a lot of Notes (bug-reports) asking for many businesses and buildings to be added.
There was a stage when mappers were content to only add point nodes for a few businesses and call it a day.  In other parts of the world, even in the US, business buildings are being fleshed out with multitudes of parts for a 3-D rendering.  Also, I see little in your area of private houses, garages, even sheds, that are standard in many parts of the world, and with time and enthusiastic mappers,  will certainly be seen here.
I had, before my crash, discovered a well-mapped neighbourhood with every private drive to every house marked and more details than that, also within the US - somewhere.  I could trivially point you to a smaller town where more than 5 years ago an enthusiastic mapper drew in every single house and driveway, creating an island of detail, which over time has become surrounded by a whole countryside of detail.  But that's not here.
Different mappers work to different standards in different areas.  Perhaps this mapper only worked in the one smaller area.  But as a general rule, we go by the philosophy that mappers are building upon each others' work, and do not take kindly to tearing down that work without good reason.  Something you don't see as sensible, may quickly become established.  Suppose I draw in an island of private homes, sheds, and garages nearby?  Will you delete it too because it's out of place where the default is only street lines?
Or because there are no housenumbers?
A private drive is a simple linear way to express there is a residence or other building that my skill level can't map to my satisfaction, or to orient where surveyed housenumbers should be mapped.  There is also a firm that is adding them for the aid of, well, let's say paperboys as an easy-to-understand shortcut - I think US postal laws limit adverts into the mailbox to the Post.
.
You will never find consistency in a project like OSM with as many different ideas as thousands or millions of mappers.  Only if the number of mappers dwindles down to nothingness, or if orders from above arrive from Our New Ownership (all hail Niantic) to map in a particular style, only include this, exclude that, and lakes belong everywhere.
Remember, you may think drawing the homes is more important *before* the driveways, but you can't decide that for everyone.  I'd rather leave buildings with more than six nodes, or which I can't see in zoomlevel 21 imagery, for a better mapper than myself and do what I can to improve the map within my limitations today.
.
The building you added/modified is an interesting case.  I think it's in its third revision; apologies if I didn't note your name carried through.  I know it's got some magic that breaks the normal tools to follow its history.
It caught my eye due to your wish to map buildings from a smartphone/tablet (you said Android), and a good example how you've started with something complicated, my first impression was that it had gotten worse than in v2.
Making perfect 90° angles is important - my editor has the quadrilateralise() function that does mysterious mathematics but somehow fails when I have too many nodes, or too close - I've not tried to understand the math.  Your chosen building also has a semi-hidden 45° roof side, and I believe others.
Good that you have found the better imageries.  Never having used the Best Editor Of All, JOSM, myself, I have read the best buildings come from a plugin dedicated to providing the tools to draw as perfectly as I would like.
I still don't know if a touchscreen is helpful.  Then, even with a fullsized tablet I can never use the kezboard as I like (where an IBM Model M clickety-click is the Holy Grail), always inadvertently hitting wrong functions; and for editing, a mouse can give me pixel-almost-perfect precision, rather than the many-cm inaccuracy of me fat fingers.
.
All that aside, I'm going to try and visualise your building history here.
And please keep in mind, OSM does not strive for a uniform standard, or style, or level of perfection, but always tries to get better.  I'd love to point you to many examples of Best Of OSM (or Worst) to show what others are doing, right or wrong.  Some of these are examples of Tagging For The Renderer, a trap into which you have appeared to have slipped by referencing the appearance in your Pokémon Go, which is only one of probably thousands of depictions of the map data, and but one of millions of users ranging from businesses to goverment agencies.
Hope that clears things up.  Your work was snared by a watch I'd placed out for a simple form of hotel SEO vandalism - deleting well-mapped buildings, service drives, pools, car parks in the vicinity of a hotel, presumably to make the advert marker for it stand out, so don't think I've got it in for you (I do ;-) because I want to see how well you can map from Android).
