Most physicists don't think about other universes with other physical laws because they don't really affect what we see.
Cosmologists interested in fine-tuning might.
Quantum foundation theorists often consider alternatives, not because they think they are real, but because it's useful to understand why QM has the form it does. Mostly their results suggest QM is difficult to modify without becoming trivial or useless.
I think the drive comes more from the metaphysical direction. It's hard to imagine why one set of laws would emerge as physical unless all sets of laws are physical, just by virtue of existing mathematically.
