It is impossible to fix the 'inscriptions bug' at this time. Maybe there was a small window in 2023 (maybe - it's not guaranteed) with enough social and technical pressure it could have been 'addressed' with a very aggressive change in relay policy.

But now? No way that ship has sailed. Only a very small percentage of nodes need to relay a transaction to have it get to miners, and generally speaking miners like fees.

Op_return is 4x as expensive as witness script for its size.
