If setting a repo file to enabled=0 breaks something, then no one
should be using it in the first place.  As for support, does that mean
you'll come fix my box when a different 3rd part repo adds a package
with the same name and the packages clobber each other during updates?
 If not, how is not having your support any different?

And yet, everyone has policies that keep them from accepting all
packages into one repository.  Lovely...    And worse, where the point
of the repo is to supply updated packages, they often aren't renamed
and intentionally conflict with others.

I'm sure it isn't.  But it would serve the users that need packages
they each refuse to accept.

Hmmm, that seems like a bug.  Should rpm packages clobber user configurations?

The underlying problem is that there is no correct way to deal with
uncoordinated repositories.  Maybe someone could tackle that problem.
Coordination seems to have failed even in the simple cases where the
idea is to be conflict-free.   Maybe a brute-force test integration
against all known repositories and all packages could come up with a
matrix of what works together and what doesn't.
