I agree, but that kind of goes to my point:

I believe the vast majority of researchers in quantum computing* spend almost no time on metaphysical speculation,

*Well, those on the "practical side" that thinks about algorithms and engineering quantum systems like the Google Quantum AI team and others. Not the computer science theorists knee-deep in quantum computational complexity proofs nor physics theorists working on foundations of quantum mechanics. But these last two categories are outnumbered by the "practical" side.
