I just don't want to see incentives to route around our peer to peer mempools with things like slipstream. As much as possible, I hope all miners can be on a level playing field. Once I finally get my bitaxe setup, I want to be able to compete fair and square. This is obviously on a very small personal level, but when this scales it may be critical to mining and bitcoin's decentralization. It is my understanding that other standardness rules are important for ddos and other attacks. The op return limit is not. I would probably be in favor of a consensus softfork that limited blockchain spam without negative centralization risks. But that is quite unlikely unfortunately. Sadly, 4mb blocks/transactions of crap are possible. Will blocks be heavier without the op return limit? Maybe, but I believe negligibly so. I'm more concerned with centralization risks, utxo set harm (I think this may have a greater impact on costs to run a node than any potential small increase in storage costs.), and making it harder to securely maintain bitcoin core. I'm no one significant here though, and am just regurgitating information. But it is information obtained from multiple well regarded 😉 minds past & present of bitcoin, and it makes sense to me. Best to you and all of us! but I need to step away from this soon. Rainy day, but when that passes, I need some rays!
