Both full rbf and sub sat fee txs made it through what could well be called fully deployed filters. The op_return filter specifically created a perverse incentive that led to counterparty, omni, and stamps embedding data in outputs, which is strictly worse than if they could have used op_return instead. The rule should have been relaxed a decade ago in my opinion.
Discussion
I stop engaging now, there are really no facts we could discuss about, I would like to see some data. Nobody thinks filters will prevent any non standard tx going through, but they rate limit them enough to not impact the intend of the network.
