I would prefer to keep the filename the same as long as the format is
the same. (Not a suggestion to change the format.) bdist_wheel is easy
to edit but pkg_resources.py is not because it has a long release
cycle and if you make a mistake you will break almost every Python
installation. Right now a new class attribute Distribution.PKG_INFO
keeps track of whether the PEP-defined Metadata 1.0-1.3 is called
PKG-INFO or METADATA. To support REGISTRY in pkg_resources you might
do something similar, changing line ~2319

self._get_metadata('entry_points.txt'), self

to

self._get_metadata(self.ENTRY_POINTS_FILENAME), self

or

for name in (possible, entry, points, filenames):
    ...

defining ENTRY_POINTS_FILENAME for both Distribution and
DistInfoDistribution, and you would have to wait for a new distribute
release.

In other words, it is a hassle and the feature is the same. An
entry_point is always an entry_point. It should no sooner be confused
with an English "point of entry" than keywords like "print" should be
confused with pressing books.
