That's a good point. There is definitely some physics content in the interpretation of quantum mechanics---Bell's Theorem certainly took many physicists by surprise when it came out, since it proved people were arguing over more than words---but in any case it's all a tiny higher order term in the series expansion for 'physics'. (The 0th order term is "Newton", FWIW. ;-)
