It is the nature of the beast that makes it undesireable.  I have seen one of
the shops here in town tear down a j valve and when they rebuilt it, managed
to reinstall the handle that the pullrod attaches to upside down.  In the up
position, it would allow you to breath the tank dry.  This was a reputable
shop.  Now *I* know how to avoid that, and I know how to test for it, but
people make mistakes.
Since I check my pressure regularly during a dive, I would have a pretty good
idea of where I stood with my air.  If I was deep, I'd surface then.  On a
shallow reef, I'd probably stay a while longer.  What I wouldn't do is make
another dive until it was repaired of replaced.
You are the one who keeps claiming that the J valve is an adequate backup.  I
don't believe it is.
No.  The housing is not going to go boom.  The bourdon tube and the gears
attached to it will probably freeze from corrosion.  The end result is a
gauge that never moves.
I'm sorry that happened.  I would have taken your side in that situation.
Being underweighted is a major PITA and detracts from the fun of the dive....
if you're even able to get down.  You say a couple of people wished you'd
drowned?
They get plenty of complaints.  You still want those numbers?
Au contraire.  It's a matter of assessing risk, and then choosing the path
that minimizes it.  Diving has many parallels to flying.  One of my maxims
was that if I was beginning to worry about fuel, I don't have enough.  You
could easily say the same about air.
