100k op returns are being mined into blocks, and nodes have to take them to not fork. Removing the 80 byte op_return limit allows core to make transactions with larger op_returns. But most people don't use core to make their transactions. Removing the limit also allows those transactions into a (core) node's mempool. But if you don't let them in, and don't relay them, that does not prevent them from being mined into a block anyways. People (spammers) will get those transactions to miners out of band if core/knots is not relaying them. Not removing the op_return limit is putting your head in the sand, and incentivizing a buildout of an out of band transaction market controlled by centralized entities.

Same BS argument as “back alley abortions”
We need to make abortion legal otherwise women will die on the streets.
We can just do the right thing and not be part of the problem.
Picture this scenario: Core and Knots chose not to relay large op_returns. Meanwhile, the biggest KYC miners controlling around 90% of hash rate and don't gf about reputation put up an API for pricing and direct submission of transactions - fast and centralized. They mine the transactions into blocks and send them out to core and knots. Core and knots, not seeing a complete mempool, now have broken pricing, and wallets start connecting to the miners' API for better UX, because they're fast (centralized) and have more accurate market pricing of sats/vb.
Sounds like a plan.
The fee estimation is insufficient to take on the known and unknown risks imo.
This is only important if you need to get in the next block. Anyone can go on mempool.space to verify their fee estimation is in the ballpark. It really is a non issue
Price signals is everything to a market. I am strongly opposed to some centralized service that is capable of more accurate pricing than the network itself can provide.
It's "SIMPLE" all they have to do is create a completely separate gossip channel to a miner and make it worth the miners time to not only incorporate the transaction into EVERY new block template they have to create until they mine one. But also, make it so expensive that the miner doesn't mind absolutely destroying its reputation.
It's just that EASY.
Or you could stop being a spoil-sport and relay the spam for them so the miners don't have to put their necks so far out...
It's almost like there are some nefarious incentives at play here.
