I made it very clear in my mail that I'm not suggesting that we should throw
RPM away.  The question I asked is supposed to give one an idea of how much of
the problem is caused by the current implementation as opposed to the inherent
complexity of the problem.

What exactly in my paragraph you quotes is "a severe mis-reading of the
discussion"?  You say the exact same thing as I did except that instead of
calling RPM a lost case as I did, you call this approach making
apt/smart/zypp/etc. even more of a second class citizen.  End result is the
same pig: use yum or be screwed.

You and Seth seem to be on the camp that thinks it's no big deal if one uses
RPM directly and gets into a suboptimal state.  Some of us think that that's
unacceptable.  We disagree and that's fine.  Whoever ends up doing the work
decides what to do.  I fully understand that and don't mean to imply what
people should be working on.  Hope I've made myself clear this time.
