I know you're responding to a bunch of people arguing different
things, but you and I are in agreement that when it comes to the
*core* testing framework, an out-of-distro Python installation
requirement is not what we should be targeting for "supported
platforms". And I don't think we're going to need that.

I have a much harder time agreeing with this. The end user experience
we're going for is
$ sudo dnf install python3.12-pytest
$ meson configure -DPYTEST=pytest-3.12
$ ninja reconfigure
...
pytest : /usr/bin/pytest-3.12 7.4.2
...
plpython : YES 3.9
That's not a burden. I doubt we'd be able to achieve that right away
with all of the PG15 supported platforms, but it's hard to believe we
couldn't get there eventually. (The above is from Rocky 9.)
