I also don't see the need for #1, but how much of a problem is #1? Or, 
as mentioned on irc, is that an ansible only issue?

Please note, that we still have the python-is-python3 package, which 
currently is ok to use, the package description says:

  No packages may declare dependencies on this package.

So you can use it in autopkg test triggers and build dependencies.

Shipping the /usr/bin/python symlink in an existing package will make it 
much more difficult to get rid off it later again.
