You'd run into the exact same thing if you updated, say Mozilla,
from
one version to one that's incompatible with the old one. You'd need
to blow all the users' ".mozilla" directories away in that case. Why
go through all this? If a given user has a problem, then have them
delete their app-specific directory and let them reconfigure the app.
Actually, that's a good example to pick on (Mozilla or Thunderbird).
You (might) want to discard old configurations that might have
conflicts, but keep bookmarks and mail. So you have to be choosy about
what hidden directories you erase.

There is no point trying to privately email me, I only get to see
