Please note that taking one-off backports to stable trees, increases our
workload over time and almost always is not the correct thing to do as
it diverges code streams.  So while this seems simpler "up front", from
a maintaince point of view, is almost always the wrong thing.

That's great, but we really would want the original commits here, OR
approval from the relevant maintainers that "yes, this is really the
only way this can be done for stable trees".
