No, that is absolutely not the point people are making. They are saying that a pool operator configuring their preferred MAX_OP_RETURN_RELAY value is somehow "an attack on Bitcoin". They are acting as if this setting is an ephemeral core parameter. It's literally designed to be and intended to be configurable.

Who is they? That was the point I was making, I think we've been shouting at each other in agreement 😅
I assumed when you said that you don't have to "accept my changes to the design" you were referring to Knots decision to include a different default value. As if altering an intentionally configurable value is "changing the design"
