I do tend to agree. If it used to work, it should continue to work, even if it wasn't _meant_ to work.
That's not always 100% possible, but the fact is, neither is updating user space always possible. The kernel needs to try its best to maintain stable interfaces, and no, "..but the interface was broken" is _not_ an acceptable excuse for unbreaking it if it causes problems.

Yes. Leaving everybody wondering whether it's just an opinionated expression of the former problem, or whether there is a real and understandable reason why it was NACK'ed.
