No. That's what the perl-forward-compat package has been for:
http://download.fedora.us/fedora/redhat/8.0/i386/RPMS.stable/perl-forward-compat-5.8.0-0.fdr.2.i386.rpm
Seems reasonable, only that it is yet again different than how it is handled with python. I know the situation is a bit different, but the implementation is completely different. (naming and how versioning works)
Yes, it's different, but it was subject to public discussion [1], and none of the few people who had comments disagreed strongly.
With the new and automated 'python(abi) = ...' dependency in FC4 devel, the solution on the Python side has become even more different, btw.
MODULE_COMPAT was designed to allow for distinctions of more than just the version (which is all python-abi does). This is necessary for perl and not python because it is possible to rebuild perl in different ways that breaks ABI compat, while python is almost entirely noarch. This happened with the perl package IIRC in the RH8-RH9-RHEL3 timeframe.
Since then however perl has not broken ABI (?), so it seems that we have this seemingly overcomplicated construct. But if we do break ABI again like in FC5 because we recompile the same version of FC4 perl with some new flag, MODULE_COMPAT can enforce exact deps and prevent incompatible FC4 packages from being installed on FC5.
Chip put a lot of thought into designing this.
