When will it not be too early?
IMO at least after porting to python 3 few crucial applications.
One of the most important is gimp.
Even more important would be getting rid of python 2 out of the @base and @core kickstart profiles.

Gimp has another tail in form of gtk+2 dependency but IMO cutting python 2 dependency is way simpler task.
BTW: cutting off gtk+2 dependency is probably as same as python 2 important.

Python 3 is now almost 10 years old. The "Python 3 as Default" change
was for Fedora 21. Python's documentation has a section on porting.
There are printed books about porting. There's a comprehensive guide at
portingguide.readthedocs.io. Fedora's Python packaging guidelines say
"If it supports only python2 then [...] upstream SHOULD be contacted and
encouraged to rectify this issue." -- have you done that?
We're honestly tired of making calls to migrate. What would another one
of those accomplish?

Try the Python SIG!
Possibly .. however IMO python 2=>3 issues simple only massive and less complicated than ggenerally all python issues.

Why have you waited so long?
To have a bit more time to do this. Recently I've been a bit more busy and month ago started new contract in Brussels.
Will try to do this probably in the end of this month (with add use more %lang() in mc.spec which I have in my own version of this file)
