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.

> Disruptions to the ability to use Bitcoin as money should be avoided One can make the case spammers have significantly disrupted the ability to use Bitcoin as money for the past 3.5 years. Maybe send your grievances to them instead?

Your response tacitly acknowledges that you think there should be no more forks / updates / fixes, and that bitcoin should ossify. Arbitrary data has definitely disrupted the usage of bitcoin as money over the last 3 years. Have you tried syncing a node recently on an older but still fairly capable laptop. Syncs very fast until about 70%, then completely hits a wall, with an estimated time to finish of over a year. This forced me to spend $800 on a more powerful machine. I suspect that most people will turn away from that and therefore a lesser ratio of people using bitcoin will run nodes. This does not just disrupt bitcoin as money, but also disrupts bitcoin as a decentralised network.
