You should be - Why? In case something in rpm changes, packages from 
different fedora releases will be incompatible and broken to different 
extends, independently of their NEVRs.

This situation is quite realistic - We've had this kind of changes 
several times before. It's just that this has not happened in recent 
past, which probably is the reason why people have forgotten about it.
