Can someone compare the main branch (commit e4044e9f893350b4623677c048d33414a77edf55) to the main branch + PR 28427 patch?

You can download the patch from:
https://patch-diff.githubusercontent.com/raw/python/cpython/pull/28427.patch

How can I build Python with PGO on Windows? Visual Studio has two profiles: PGinstrument and PGupdate.

I cannot find "PGO", "PGinstrument" or "PGupdate" in the https://devguide.python.org/
