[Distutils] Pypi to enforce wheel, python3 - is it possible?

[Evgeny Sazhin]

My experience so far tells me otherwise. Our of 7 or so libraries that I
tried to convert to wheel files that salt stack depends on only 2 were
using setuptools, others were using distutils and had sometimes quite big
setup.py files and were not compiling out of the box, and frankly I have no
idea how I can create a wheel from a setup.py file that is taking 10
screens to scroll and not using the packager that is supporting wheel and
has dependencies on some C stuff.

I think the notion of sdist being a magic thing that everybody should be
able to make anything from doesn't actually work for end users.

I think sdist has it's place but the guidance that people need should be
quite explicit about how and what to do to end the confusion.

Standard is standard and should be set in stone as such. Otherwise
everybody keeps wondering around and doing whatever they see fit and
effectively creating a mess without the ability to sync on common ground.
like java jars are the standard way of distributing the libs, same thing
should be with python packages. Everybody should know that wheel is that
thing, nothing else. Doesn't it make sense?

Thanks!
