As most of you are now aware, Python 3.10 deprecated the use of

I have begun a branch to deprecate distutils (and basically remove it's
usage from oe-core).

I have another branch to drop distutils completely, but I will hold off
on that for now. The intent is to merge deprecated_distutils first.
One big sticking point is the use of distutils.version.LooseVersion,
which is recommended to be replaced by packaging.version.Version. This
is one thing that is difficult to replace directly with other libraries
in CPython core.
A key place where this is not obvious how to replace is in
sanity.bbclass. Our easiest path forward would be to require the host to
have 'packaging' (pip install packaging, etc.). We could also wholesale
lift LooseVersion and add it to lib/bb/.
I think this should be fine approach, which can perhaps sail the
migration through and then we can unbolt it, like what we did with lnr
Please speak up with your concerns about the branch or ideas about how
to handle the removal of LooseVersion.
There are additional changes around Python packaging (egg-info => wheels
and setup.py => pyproject.toml), but that is a separate conversation.
Cheers,
