It's also not clear if there might be changes again during ratification without changing the version number, which wouldn't be ideal (though probably just about livable given it's marked as experimental).

I agree that the incompatible change is highly sub-optimal.  I've asked around a bit on the status here, but nothing I would consider "official" or would want to quote someone on.  My overall take is that we probably should take this as experimental, but only with the understanding that it may change in incompatible ways.
