According to FPC decision, we only obsolete removed packages that would cause troubles (dependency issues) if they stay installed on the system. What's the trouble with python2-copr and python2-hwdata? Could you please provide more info?

When removing py2 package, don't obsolete it from py3, but rather obsolete it from fedora-obsolete-packages but only if keeping that package installed is likely to cause problems on upgrades.

I did not know about this "but only if". No, they do not cause the problem on upgrades - now.

My mental problem is that I am the maintainer of those packages and I feel bad for leaving leftovers on users machines.
Personally, after each upgrade (I am oin F29 now), I check rpm -qa |grep fc28 and consider manually removing retired packages from my system (skipping packages with FTBS issues).

I as maintainer have no clue when the requires 'python(abi) = 2.7` or any other transitional depends on some 'python2-*' packages will break the upgrades or even updates.

Therefore I think acting proactively is a better way. If you think otherwise feel free to close this PR.

I think we should obsolete all retired/removed packages. FPC thinks we should only obsolete "if keeping that package installed is likely to cause problems on upgrades".

So I'll close this, but feel free to query FPC for more info and/or provide an example how those packages cause problems on upgrades.
