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

[Evgeny Sazhin]

Hello,

It seems that according to the
https://python-packaging-user-guide.readthedocs.org/en/latest/current.html
it is more or less settled that the setuptools/pip/wheel is the way to
go forward.
One of the problems though is that there is plenty of packages on Pypi
that are not there yet.

Is there any plan to create some incentives for package maintainers to
provide WHEEL files together with source archives?
May be Pypi could say that starting from such date it recommends to
supply the wheel with the source and then starting from such date it
will require it?

There is probably no better way to make the things move faster like
the central repository committing to the certain way of doing things.
Is that possible?

Same thing could be done with python3 - ask people to provide py3
versions along with py2, and then start requiring the packages to be
python3 or universal.

Any opinions? Does anybody know if there is already such initiative?

Thanks,
Eugene
