We all must realize that incremental improvements are not harmful. Delay is
harmful; there has been no obvious way to make a Python package this decade
based on the idea that something better might be just around the corner or
that the current way will be deprecated.

The goal of this version of the PEP is to better represent important
setuptools metadata statically while imposing as near to zero cost as
possible on the actual setuptools users. They will not welcome an unproven
alternative that requires work on their part. Instead, we change things a
little bit, support setuptools / distribute OR "something else" for 5
years, until "something else" is obviously, compellingly better.
