I think my reasoning was that it was not a bug fix so it wasn't a strong candidate for a maintenance release. But feel free to backport it if you think it important.

It wasn't: 004fe3449193 deleted it. It appears that an incorrect merge from 3.4 (3f4abe3107ce) in a subsequent set of changes for Issue21823 brought it back to life in default.
