Well, we would need to have enough sense to migrate data when we
deprecate.  Once we deprecate 2004.3, we would copy the 2004.3 stuff to
2005.0 and break the inheritance on 2004.3 from 2005.0 and so on.

As for deprecation, I think we currently have a loose rule of 6 months
after deprecation for the profile removal.

The only real problem with user-provided profiles is the simplicity with
which a user could completely hose their system and our complete lack of
ability to troubleshoot problems with them.
