Gleason's theorem is sort of a special case of Born rule for the case an operator is the unit operator. There is an interesting chase after the Born rule, and some people do think that certain quantum interpretations give the added axiomatic "boost" necessary to prove that. I am agnostic about those claims. If this does turn out to be the case I would give the best bet to either MWI or QuBism.
