Been running my server without python2 since… 2019-11-16 I thought it 
was more than that but still quite a lot considering that I kept clang-8 
for a while before switching to clang-9 on it. (I use clang as main 
compiler, I'm also deprecating gcc so prefer to play it safe)

I still have a bunch of stuff on my desktop&laptop requiring python2,
like nodejs or renpy but it's getting quite better in the last months,
one I'm trully fearing about how it will go is dev-util/scons, I guess
a lot of patches will be required on the releases.

I think this kind of discussion might be better on the forums or
a user list btw.
