you're leaving the boundary of testable physics

It has been shown experimentally long ago that MWI requires full Quantum Gravity, not just Quantum Mechanics (plus Newtonian gravity or General Relativity, or even semi-classical gravity).

EDIT: provided an alternate link (paywalled, sorry).

Who out there, MWI-adherent or not, seriously thinks that QM is a fundamental rule of nature for everything BUT gravity?

My position here is Knightian uncertainty -- I have no idea whether that's true AND I have no idea what are the chances of it being true.

That's, umm, nice, but I don't see how it helps answer the question since I suspect the number of 'not me!' would be enormous.

Not sure what you are asking, but Everett and many other MWIers certainly thought/think that "the wave function of the universe" is all one needs to know.

for everything BUT gravity
