Hm. I think it'd be ok, given that python 2 is well past EOL. But I also see
your point.

But this is probably a good compromise. Were you thinking of doing a proper
autoconf test or just putting something like python3 --version || true in
configure?

I guess it'd be easiest to interpret if we output the current PYTHON version
and, iff < 3.0, also output the 'python3' version?
