The change itself comes with related api-ref additions that help. Also, we
wrote that fix for a good reason : to prevent operators to shoot their feet
without knowing.

Consequently, I think we shouldn't leave away the opportunity to backport
all changes (incl. the api-ref ones) and just make sure we release a .y
stable release.

That said, Operators, please take notice of the context of this bug and
raise your concerns if you have any, please please please.
