This is a bunch of BS. It's not a minefield, and you can change that
function. Mathieu is perfectly fine in modifying his code to deal with
it. He has several times in the past. But I did not agree with the

the straw man with this.

Good grief. No! The reason maintainers refuse to add them is that
userspace can depend on them, and if that happens, it becomes an ABI.
Stop with this nonsense.
