One important point, you are (or have been) effectively dropping support 
for every distro prior to FC1. Also perl offers compatibility with 
multiple versions, I guess that's why you want this (so a perl security 
bug allows you to ship a newer perl instead of backporting the fix).

I'm not sure if the advantage of this strict/loose dependency weighs up 
against the disadvantage of dropping everything that came before FC1.

I don't see a problem with no versioned dependency, since the only case 
where this really is a problem is when people install a package from 
another place (you don't have control over that anyway) or Fedora Extras 
ships suddenly without some perl module.

If there was no disadvantage I would probably embrace this as much as the 
next guy.
