I don't have a PR in-hand. I just ran across this when trying to explain 3.9 vs 3.10 timings and M-1 vs Intel timings. Ideally, all of these PRs should be reverted. Short of that, each change needs to be reviewed to see if it created extra work inside a loop. There are 35 calls to PyLong_GetOne and 3 for PyLong_GetZero. Each of those should be checked.
