I think they only way out a a compromise.
Litecoin is now activating segwit.
http://litecoinblockhalf.com/segwit.phpThis will be activated.
Putting bitcoin in a different position because segwit will be active on a main coin network and tested.
It will just take time to realize that , Miners want to be sure of a job , but users dont want miner dominance.
Dominace of any group is what we dont want in bitcoin.
Its also not true that a s9 == btcU , because you can choose the pool you mine.
Is asicboost a problem? well it should be overt , and the question now it is discovered.
if you need to mine empty blocks is not a good thing , not allowing mining empty blocks on a full network, should also be a feature.
