Hi,

Please consider the "legacy" build mode to be strongly deprecated, both
in distutils-r1 and upstream (to the point that sole presence of
packages installed that way triggers deprecation warnings elsewhere,
sigh).  Therefore, if you haven't done that already, please look into
converting your packages to use PEP517 builds (DISTUTILS_USE_PEP517,
installing .dist-info rather than .egg*).  We'd like to eventually
remove the legacy code paths from the eclass, as they are not well-
tested at this point, and they certainly are lacking, compared to
the newer code paths.

This also applies to overlay maintainers, since overlays will be
affected once we remove old code paths.

The migration guide is here:

https://projects.gentoo.org/python/guide/migration.html#migrating-to-pep-517-builds

While at it, please also look at replacing `distutils_enable_tests
setup.py` with one of the other test runners, as running `setup.py test`
has been deprecated upstream as well.  Or running `setup.py` at all, but
the latter is less likely to suddenly stop working.

Best regards,
Michał Górny
