Any such change would have to be done via deprecation, because it's a
breaking change. Sometimes, breaking changes occur immediately due to bug
fixes (though it's sometimes been argued that even breakage such as that
should be minimized), but they should not occur due to a feature change
unless the nature of the feature change absolutely could not be done via a
deprecation, and it was deemed so critical that that breakage was worth it.
There's no way that this falls in that camp.

So, if the change ends up being made, and it immediately breaks your code
without there being any deprecation warning first, then someone wasn't doing
their job properly, and you should report it as a regression.
