If you want to drop Obsoletes/Conflicts, make packages installable
together. If some packages conflict in rpm sense (i.e. have conflicting
files), packages should have proper Obsoletes or Conflicts tags.
Leaving users with --force is not an option.

If some packages are easily switchable replacements, Conflicts behaves
worse, because disallows to atomically replace package.

feature-Provides+Obsoletes is some solution, but causes problems with
old packages which didn't Provide given feature.

I feel "all" really means yum (including its UIs)

In distros which don't provide alternative packages.
Or use "alternatives" mechanism, like Debian.
