I feel you on a lot of this! But out of the box Python support? Does anybody actually want that? It’s pretty darn quick & straightforward to get a Python environment up & running on MacOS. Maybe I’m misunderstanding what you mean here.
I avoid writing python, so I’m usually the “other people” in that sentence.
That's optimistic. What if the system Python gets upgraded? For some reason, Python libraries tend to be super picky about the Python versions they support (not just Python 2 vs 3).
