I guess I should clarify that it's not like there's zero "value" in using bare multisig vs say data embedded in a pubkey-hash standard output here. There's some few bytes of savings by using one output instead of multiple; and from the point of view of coding some jpeg-tracking thing it's always easier to track one output instead of many.

But just talking in general, at the highest level, you can't stop this by disabling one output type
