If you're referring to the v12 open items list, then, no, I wouldn't
think it would be as it's not a new issue (unless I've misunderstood).
Only regressions from prior versions are appropriate for the v12 open
items list, long-standing bugs/issues should be addressed and fixed, of
course, but those would be fixed and then back-patched.
