I would like something that auto-generates the python classifiers (say in a SetupKwargs plugin). Has anyone else done something like that? Looks like the pants wheels are not released with the python version classifiers, so https://github.com/pantsbuild/pants/blob/main/pants-plugins/internal_plugins/releases/register.py#L95-L104 does not use them.

Hrm. Yeah - pantsbuild.pants is weird. We distribute it on PyPI but we really don't want people installing it. We want them to use

./pants

or

pants

or the released

pants.pex

; so the textual classifiers don't serve quite the same role as in ~normal projects intended to actually be directly used or pip installed.
