Wow. That's quite a leap. I have not argued for the spam chain. I run Knots. I think that a soft fork is probably a good idea.
But I still don't see how only 20% of us can force miners to mine blocks that follow BIP444 if 80% of the nodes will accept non-BIP444 blocks
The UASF during the block size wars is a little more complex than the fact that few nodes signaled support. It was supported by exchanges and waller providers. And that amount of support is what forced the miners to capitulate.
Do we have that level of support for this soft fork?
