Ugh! :)

If it was universally okay to add Python as a build dependency, I'd have
done this already. The rules format could be yaml, json, toml, or
something supported by Python out of the box (not xml though!). The
whole thing could be 100-200 lines of Python without a hostprogs build
step.

drm/msm has quietly added a Python build dependency a few releases ago,
and I'm kind of still waiting to see how it plays out...

BR,
Jani.
