Having two interfaces guarantees failure. What's the separation

Let me put it another way, compatibility cannot be an after thought.
We need to think deeply about compatibility when we design our
interfaces and we're going to have to redesign interfaces with
compatibility in mind. It's a hard problem but it's solvable. Just
defaulting arguments in QMP doesn't do anything to improve compatibility.
We cannot radically change our internal implementations and expect to
bridge it all in some special sauce code somewhere.
This also suggests that we're going to have to practice deprecation to
evolve our APIs in a reasonable fashion.
