Consensus around what is a valid transaction is not changing. What ultimately is changing whether MEV/MEVil is perpetuated or is decreased. The limit only serves to provide increased centralization pressure and revenue to mines for out of band payments and weakens the public mempool, which is critical to a healthy network.
Discussion
Maybe. Maybe not.
Elaborate please, happy to hear you out
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)”
Apologies for an X link, but this is the most thorough and neutral technical description I have found and recommend everyone to read and consider https://x.com/bitschmidty/status/1918257532415385742
I can definitely understand and respect your take as you are clearly thinking it through so respect there. The one fact I would really push on is, that is only one of several considerations in this change. So even if you are skeptical of that one argument, I’d encourage you to check out Schmidty’s notes on the others 👍🏻
