We try not to change the APIs of libraries that come with GHC within a
GHC major release, so that if something compiles with one minor release
then it'll also compile with another.

We do occasionally make exceptions (and most compiler bugfixes etc are
effectively exceptions), if there is strong motivation to do so. Given
how contentious this proposal has been, personally I don't think there
is a strong case for making an exception, though.
