You can do that right away. Commits to stable can be backported to any
open stable branch so long as they don't have ABI/API implications.
Even if they changed the selected IFUNC it would still be OK.

You are free to cherry-pick as required. Please post your cherry-picks
to libc-stable and note that you're committing them to branch X, Y, and Z,
this way distros know what you're doing.
