I think we need to decide exactly what the goal is with splitting out
the core modules - some people think we should split them all out,
others want a smaller set.  I'm not really sure which is best at the
moment...I think it requires more discussion.

This isn't actually true.  The modules are still split out.  The changes
were to make the perl-devel require the other split modules, and include
the split modules in the default install.  You can still remove
perl-devel + co at install time or later, if you wish.

And yes, this is two steps forward, one step back.  I wasn't really very
happy with it, but enough people were going to be negatively impacted by
this change that spot and I both decided it would be best to go this
way.  I would rather have made a clean split instead of doing it this
way, but I have to accept that we didn't give enough warning to make
people comfortable with this change.

I agree.  I'll look at it Monday, unless one of the co-maintainers gets
to it first.  :-)

I'm not really sure what you mean here...what specific problems do you
see?

Yeah, I believe I've seen them on the wiki.

I think documented best practices are a good idea - if there's debate
between possible options, we can present both of them along with pros
and cons.

Again, they weren't reverted - though I take your point that including
them default is practically the same thing.

I had planned to, but was convinced that the disruption to users and
developers would be too great.  I probably should've brought you into
the discussion, considering the contributions you'd made.  Sorry!

That's my gut feeling about it - but some people seem to think it would
be worthwhile to split out everything.  That approach would make it
easier to update 'core' module piecemeal if needed to fix bugs - but
leads to a lot of packages to have a 'core' perl distribution in
Fedora.  So, I think more discussion is warrented.

Ok.  I think we have a pretty good hit list going here.  I'll put them
up on the wiki somewhere this weekend.
