I'm on board for the idea, not the exact implementation here.

Logic lgtm. Would it be possible to create a test for this?
Also lint errors need to be fixed.

Suggestion: change this to a .feature.rst file, and change the content to: Add support for editable installs for project with only setup.cfg files.
That’ll make it more discoverable and most users (and I) would consider this a new feature.

IMHO it is not quite a new feature, I was expecting that if setuptools
understands setup.cfg
-only projects, that pip
would understand them too automatically, but it turned out that pip
uses setuptools
in a bit own way. I feel like the most of people that encountered this issue were originally assumming that it would work and were surprised that it doesn't. So, it looks more like a bug, than a feature.

I understand this is a bugfix from the technical perspective, but in practice, very few user expected pip install -e
to work on a setup.py-less project before this change, and most would feel it is more like a new feature instead. The changelog is ultimately consumed mostly by people not faimilar with pip internals, so it’s probably better to mark this as a feature.

I'm not entirely sure I'm comfortable with a setuptools-based project without a setup.py
as a general concept (I don't want people to think that pip
is the front end for setuptools, and start asking for pip sdist
to replace setup.py sdist
for example) but that's a problem for setuptools to manage, and doesn't really affect this PR, which looks OK on its own merits.
