[Distutils] new PyPI: a rant from a package maintainer

[Randy Syring]

Issues created:

  * Ignore dup uploads instead of error:
    https://github.com/pypa/warehouse/issues/2284
  * Rename "/legacy" API URL: https://github.com/pypa/warehouse/issues/2285
  * Propose "packaging announce" mailing list:
    https://github.com/pypa/packaging-problems/issues/98
      o Previous issue noting challenges in communicating on packaging,
        many of the same concerns still seem relevant:
        https://github.com/pypa/packaging-problems/issues/21
  * Explain what "pre-production" means on Warehouse:
    https://github.com/pypa/warehouse/issues/2287
  * Deprecation notice added to: https://wiki.python.org/moin/TestPyPI
      o Issue created to enhance docs for TestPyPI:
        https://github.com/pypa/python-packaging-user-guide/issues/362
  * Better error message for PEP 527 accepted file types:
    https://github.com/pypa/packaging-problems/issues/99

I hope I got all the right places for those issues.

Thanks Donald for the clear reply from which it was easy to create these 
separate issues.  I didn't realize you had so little paid time to work 
on packaging issues.  I'm surprised with all the large companies that 
use Python that the PSF can't secure more donations to invest in fixing 
these issues.  Or that someone like Redhat can't get a couple engineers 
to devote time for a couple years like they do to other OSS projects. 
(No criticism intended, just musing).
