The vast majority of Bitcoin users have no idea BIP110 is even happening. Disruptions to the ability to use Bitcoin as money should be avoided.
The vast majority of Bitcoin users use exchanges and custodial services to move coins. Even if they haven’t heard about BIP100, the custodians have and they have a responsibility to warn their users or outright not permit them to transact in case of a split. The rest of the Bitcoin users who practice self custody most certainly know about BIP110.
