I had in mind advanced use cases where an application might want to
rotate the screen. You can imagine four persons playing a game around a
tablet: the UI could switch when turn switches. I admit that it might be
a bit of a small UC but there is simply no way to make that kind of
things possible if we don't give angle relationship between

I agree that developers might end up doing lockOrientation(90) instead
of lockOrientation('landscape') but I am not sure if that risk is worth
killing a UC.
