FWIW, if it was up to me, I'd make Python 3+ a non-optional build
dependency. I'd also forget about any Python 2 backward compat stuff.

I would find it very useful for code/header generation during build
time, instead of having to resort to C hostprogs. Similar to what MSM is
doing.

That said, I know there's going to be people vehemently opposed.

Agreed. Forget about that idea.

BR,
