The argument (if I understand it correctly) is that individual non mining nodes using spam filters will only push miners to link up and pass blocks directly to each other thus diminishing the effect of the mempool THEREFORE core needs to “nudge” non mining away from using these spam filters. (What is spam is in the eye of the beholder, but I digress)

The thought process is that if miners pass along the blocks the menpool will die and the miners somehow own Bitcoin. Maybe.

But maybe not: maybe the. Odds and users of Bitcoin split the network with a softfork or something or maybe something else that I’m too dumb to comprehend happens.

I don’t necessarily accept the consequentialist take that “we must change Bitcoin because (future projected possible bad outcome)”
