Perhaps it would still be useful to have rollback functionality that 
knows about packages that aren't nice to rollback - and excludes them. 
If it was a yum plugin, perhaps a proposed update could warn you before 
hand that you wouldn't be able to rollback package X before the upgrade.

There is also no way to be sure that an older version is still available 
in any of the yum repos that are defined.

I know this flies in the face of Fedora bug resolve by upstream release
paradigm ;-) , but sometimes stuff just has to work - now.
