Oh, I've already done that. I just think it should be the default.

Well, I thought there was a process for package submission, review and
what not. Of course accidents happen. But this is no excuse, or is a
"meta packager" like yum not better than plain rpm in itself?

As far as I can see, I have to solve about as many problems as I did
without a metapackager (--obsoletes, --exclude=..., etc...). The job of
a meta packager is making things easier.

My praise was precisely that yum has had a giant step towards this goal,
but there are definitely corners to round.

Anyway, loops are not that hard to find, just mark where you've been
previously (prolog 101) and handle apropriately (ie, until repo fixes
it, I can't do anything that touches foo, bar or baz, may I proceed with
the rest?).
