Well, if we definitely intend to commit a compatibility-breaking
change, I think it's better to commit it sooner not later. If we
wait till v20, all we accomplish is to give users another year to
write code that depends on the old behavior.
However, usually at this stage of the cycle the answer to such
questions is "let the RMT decide". Take the question to them
(cc'd).
