@woodruffw I have some doubts about the ### Installing libraries, ### Dependencies for libraries, ### Setuptools vs. Distutils vs. pip parts: looks like a lot of this is now outdated, especially with PEP 668.
We can either rework it in this pull request, or do it in a second batch.

I'm +1 on doing it in a second batch, to keep things small here.

@iMichka, is there anything you wanted to add/update or are we good to merge?

I think the open/unresolved discussions can be handled in next round given that it looks like we were planning another rework?

We can expand any exceptions as necessary. I've created a table of various formulae in Homebrew/homebrew-core#167905 and will be triaging them.

@cho-m I resolved the different comments that were made. We can merge as-is and iterate from here, you are right.
