Oh no no no, this is way too big a change for 3.13. The file system layout is fixed from beta 1 - changing in 3.14rc2 is a big enough breach of our compatibility policy, but this one should definitely be reverted (as annoying as that is for people with other projects that provide this file).

Our own references to the header should be relative (i.e. #include "lock.h" rather than <lock.h>), and so putting the Python headers below the other headers should work fine.

GH-137166 is a backport of this pull request to the 3.13 branch.

Sorry, I created the revert PR here #137166 but it does mean that this issue will be forever in 3.13.

it does mean that this issue will be forever in 3.13.

Yeah, that's the nature of compatibility! It also means that anyone whose #include <lock.h> currently works will continue working, which is the more important side of things.
