Now that you mention it, I guess only true Omnipotence would be a sure win, since causality alterations themselves are also events in their own right, with their own kind of causal probabilities.

The term "Omniverse" is almost always incorrectly used, including by professional writers, and it is clear for everyone that no given character can possibly manipulate the entirety of fiction. So by sticking with a relative in-universe definition of the word (the entirety of a given fictional continuity) we are simply going with the official flow.
