Should redhat-release be versioned or unversioned?

[Bruno Wolff III]

While looking at bug 1044675 I noticed that redhat-release is unversioned 
in fedora-release and versioned in generic-release. I would expect it 
to be the same in both of these packages. I think it probably makes the 
most sense to version it for anything that is still using that, but wanted 
to check if other people had good reasons for doing it one way or the 
other.

P.S. To resolve the actual problem, I am going to change a reference 
from redhat-release to system-release, which probably should have 
happened a while ago.
