Which is a fine intent, it's just the running assumption is that if it's in the
documentation, it's supported (e.g. the distutils discussion). So no matter how
carefully we document something as unsupported, people will still argue that
it's supported because it's in the docs 🤷♂️

We'd need Mark to weigh in (or possibly track down and ask a colleague), but I
expect the assumption is that subprocess.Popen("python") searches PATH first.
I've honestly never encountered anyone who deliberately depended on the
application directory search (at least the first time, some who have discovered
it have used it, though it tends to surprise colleagues when they do).

No rush. We've got the sprints next week, and I don't have any major time
consuming projects, so will probably get a few easier PRs done. Looks like I
can edit your PR, so I can finish it up if you want to just move on :)
