I support this. When we add support for 3.15, we should probably allow None for the parameter in a sys.version_info >= (3, 15) branch rather than adding another allowlist entry, though. (We could maybe do that now, so we don't forget?)

Hah, I was actually deliberating myself whether we should already add the 3.15 branch, but decided against it due to our general policy. But if you had the same idea, I think it makes sense to add it.
