This seems like a regression, unless I'm missing something?

The reason we have it is so we can build a single binary (per OS/ABI combo) that works on older Python runtimes even when the build machine has a newer Python; without accidentally regressing on the range of versions supported.

Just to be sure, can you run workflows on your side to catch whatever regression that may arise from this PR?
