How would the Bitcoin activate Schnorr Signatures, Erlay, Taproot, and other soft forks to improve the network, if the miners "play politics" again?
Segwit threatened the ability for Bitmain or others to use covert ASICBOOST. I also think large miners favored establishing big block precedent (vs. Segwit) because they were putting short term rational interests above long term network health. They perceived cheap fees as a quick ticket to mass adoption. They also knew the increased orphaning risk of big blocks would hurt smaller miners more and help them consolidate hash rate share.
These upgrades don't seem nearly as contentious for miners. Why would they be opposed to signature aggregation, or bandwidth savings, or smart contract capability?
