Well, for b), we still have: Provides: perl(:MODULE_COMPAT_5.10.0) in
the perl RPM, and:
Requires: perl(:MODULE_COMPAT_%(eval "`%{__perl} -V:version`"; echo $version))
In all of our Fedora RPMs. The way the 5.10.0 rpm is now, that will
require that all of the perl RPMs be specifically built for 5.10.0
before they can be installed. When 5.10.1 rolls around, we could
either:
1) Return to creating the permodcompat directories, and include Provides
for both 5.10.0 and 5.10.1.
2) Rebuild the whole darn world (and make people download all those
updates if we do it during a release).
Neither seems particularly appealing to me, to be honest. But if we
already know we're going to do (1), we might as well leave the rest of
the perlmodcompat spec stuff in.

Yes, I agree.
