I still am curious as to what the difference is besides the nodes being able to signal to the ecosystem in a slightly easier way through a GUI that they wish larger blocks. Is this it?
The real difference is that nodes can easily set and adjust their limits to keep following the consensus as it emerges by way of the block emission.
And miners can use node settings information to coordinate their response to changes in demand.
I think that's a novel and beautiful contribution by BU.
