Comment (by jmroot):

 This only affects from-source installations, right? In which case, this
 seems more like a dependency that should be installed when building
 setuptools-based projects from source (since it's not needed at all when
 wheels are available or when using other backends like flit or poetry),
 rather than a runtime dependency for pip in general. Pip is supposed to
 handle dependencies after all.

 If pip installs into the wrong directory when using `setup.py install`,
 that also seems like a further bug. A lot of our ports still install that
 way and it works fine.
