The mayor problem with roleback is that you can't reverse the changes 
done by scriptlets in RPM, so it is not posible to do downgrade in a 
safeway.

EX.

rpm -ivh foo
rpm -e foo

these commands add a package and remove it again.
the state of the system might not be the same before and after these 
commands, so a safe rollback is not possible.
