I have said this to knots people but the fundamental disagreement is that they believe filters work, even if its not a perfect solution. my take is that the only reason it seems like its not working is because there isn't a lot of incentive to use larger op_returns except for one off trolls. there are protocols like OTS that use it frequently, which is why you see 99% <80 byte op returns. if there was a protocol that used >80 bytes then i'm sure we'd see that change. it's not because of the relay policy (imo), its because sha256 merkle root hashes for things are usually all you need for these kinds of protocols.

seriously, this is so helpful.
