physicists don’t, as a whole, consider MWI to be slam dunk
That’s because physicists, though they clearly enjoy speculating very much, tend to withhold judgment until there is some experimental evidence one way or the other. In that sense they are more instrumentalists than EY. Experimental physicists much more so.
“A physicist answers all questions with ‘I don’t know, but I’ll find out.’”
-- Nicola Cabibbo (IIRC), as quoted by a professor of mine.
(As for “experimental evidence”, in the past couple of years people have managed to put bigger and bigger systems—some visible with the naked eye—into quantum superpositions, which is evidence against objective collapse theories.)
