ACK for a more necessity of one more complex versioning schema in general
(but we don't need to support all variants) but we don't need to support
dev packages on PyPI - that's why a stronger version check should be

I think your mother (and most others) are smart enough to understand
and support a simple versioning schema. Bringing it to the point in
different way: "community" does not mean anarchy. Package maintainers
have a lot of freedom but as said also a responsibility for their
software  - otherwise redeclare PyPI as package t***** (I mentioned the
word already)

I don't care about subcommunities at this point. PyPI is a central
resource to Python. It is essentional for my daily work. It is essential
for me that the packages having reasonable metadata. It is essential
for me that the packages are available all the time. A certain quality
and standards are especially essential to non-professional Python
users and developers - nothing is more frustrating for those
people than dealing with non-functional packages, undocumented packages or
packages of pre-alpha quality.
