Reminds me of the Python 2 -> Python 3 upgrade. py3 was similar enough that you could make libraries to essentially support both. Users didn't really notice much difference, but maintaining lower-level libraries was often a pain. Those compatibility libraries were great, but in retrospect I think a clean break would have been better for everyone.
