Just because you don't know of any doesn't mean there aren't any. I'm
sure that there are lots who don't use bash. I'm one, and I do know some
others.

That you have seen, perhaps. Otherwise, most definitely not!!!

I suppose that depends on how important it is that the command he wants
to run on logout is run for every user. If it absolutely must happen for
all users, then no, it is definitely not a reasonable assumption. If
it's not a big deal if an occasional user slips through the cracks, then
it probably is a reasonable assumption.

Right now, none. I sometimes have lots open, sometimes none at all (and
none of them are ever bash ;-) ). I'm not sure how this is relevant...
