I agree that we should listen to people who want to build, and even make conservative changes to accommodate them. Core could start to filter inscriptions by default and engage in the whack-a-mole task of continuing to add filters that prevent and discourage arbitrary data outside OP_RETURN, then simultaneously increase the data carrier size limit so OP_RETURN can carry a little more data - e.g. for some reason Citrea apparently needs 144 bytes, so we could set a new limit a little larger than that. I think Adam Back threw around 160 bytes as a compromise number to resolve the v30 drama. That sounds reasonable to me as long as we also stomp out data embedding everywhere else.
