[Distutils] Fwd: add install_paths.json to .egg-info and .dist-info directory

[Daniel Holth]

No, PEP 426 needs to be static metadata that is not modified by the
installer.

The new json file would make more sense in (a successor to) PEP 376
"Database of Installed Python Distributions".

In wheel it would would need to be handled as a processing step similar to
writing console_scripts, or doing non-console_scripts #! rewriting, or
updating MANIFEST.

Too bad the wheel post-install is not as pluggable as setuptools egg-info
writers.
