That's right, and nobody suggested deep changes. I expressed this on

11:48 <siretart> elenril: TBH, I'd prefer to include the bump, because
                 not doing so will make backporting patches to the
                 release branch harder. AFAIUI the bump won't
                 destabilise the tree by itself

Having said this, stuff that breaks application of course should be
avoided so that we don't have to read stuff like this:

Yeah, that would be pretty annoying. But as said, 'just' bumping major
and adding a few fields to structures *by itself* shouldn't destabilize

This is what has been done (successfully!) in the last two years.

See above. I'm concerned about being able to backport fixes.
