Yeah, I can personally see a case for deprecating nonstandard features
and spitting out a warning, rather than dropping them abruptly. The
deprecation would last for one major release cycle.

On the other hand, if the nonstandard wart/feature is standing in the
way of implementing a high-quality and desired new feature (not
saying this did or didn't happen in this case; I don't know), is it
worth putting off adding the new feature rather than just excising the
wart and putting up with the pain?
