Are you going to persuade miners to run knots?
this is not uasf and It’s easier to persuade core to beef up filters rather than persuade miners to abandon core for knots.
Because knots is not as well maintained as core, it’s riskier software and would be expensive for miners to maintain.
Most miners run core!
And even if some miners switched to knots
others could just refuse rpc connection to knots and not see your node on the network as a peer, how is your node going to estimate fees on the network if it doesn’t see all txns in the block?
