SHARCRASH (2022-08-15 20:38:31+00:00): Hi! Thanks for your contributions but i think that a part of your changeset does not reflect reality, you've been too personal in your interpretation or unwillingly erased elements like obvious areas in ofrest visible on 2021 photos. You even deleted ways part of the official Bourscheid hiking route. Here at the end I will give you examples where i had similar case with ways not usable but the official route is still valid, (Geoportail.lu and guide posts still present).

From local community advise, when some highways are not usable and no traces are left anymore, please deactivate them with one of the lifecycle prefixes for the key instead of complete deletion. Infos here https://wiki.openstreetmap.org/wiki/Lifecycle_prefix This is useful for a variety of reasons:
- sometimes ways will be reused later on
- with some sources we can see there were/are ways and we need to distinguish those that have been confirmed as unusable/abandoned/razed/etc...
It is valuable data. I see you did delete some i had myself surveyed.
- as I said, sometimes contributors judge ways too much via self-interpretation like they don't deem the way usable for their activities but it can be for others. Many keys/tags allow to express the details of ways to differentiate them like trail_visibility, tracktype (for tracks), sac_scale, etc... You've done one too much personal: www.openstreetmap.org/way/777587790 This way has grids on the ground to pass over little streams (visible on 2021 photos). I don't think forestry workers would install such structures for abandoned tracks. 

Guidelines for ways in nature: 
● if the way seems very renaturalized/concealed, like very overgrown or has many dead leaves,  depending on the type of highway add/edit extra tags like trail_visibility, surface, etc for tracks the most degraded tracktype=grade5 will render appropriatly (very soft/loose material, dense grasses, uncompacted earth, dead leaves, loads of loose branches, etc),
● if you see an old track has some grown bushes or even young trees and there is still a trail, put it rather as highway=path
● if it has obstacles like fallen trunks (happens often in forests yet highways will be cleaned soon or later), add on nodes from the highway barrier=log or barrier=block + description=fallen trunk or fallen tree if it's appropriate add access=no if you think the way is not usable at all. It's good to let know others what happened with a note=bla... for contributors only or description=bla... for map users too.

Recent examples i've surveyed, barely usable or/and visible yet i haven 't deleted them:
● this way https://www.openstreetmap.org/way/1086425173 is part of several official hiking tours (see Geoportail.lu) but it's overgrown and very hardly accessible, the guide post is still there, see photo https://dgtzuqphqg23d.cloudfront.net/QbHWKGjGiPYspKjwxmE6vtq05Fwn1gQEhM5PBkDykTo-1152x2048.jpg

● this way https://www.openstreetmap.org/way/1022063082 is also part of hiking routes but it's been destroyed by forestry leftovers, see photo https://dgtzuqphqg23d.cloudfront.net/-A-wrbhFAaQBO-u6LfKtgUESLk85AEffBaXvnKNOL7w-1152x2048.jpg

I did the restorations and adapted accordingly.
