I agree, I think we should be looking it things like Op_CTV and Op_Vault. Safe small improvements. I am not technical enough to understand the risks with these two, but Iwoyuld love to see more debates/discussion on the topic.
I'm pushing back against the argument that we should accept that the Bitcoin protocol is ossified in its current state. https://www.forbes.com/sites/digital-assets/2023/03/18/should-we-be-worried-about-bitcoin-ossification/

IMO, OP_Vault could be the protocol change that brings on more governments and institutions.
Yeah, I think its naive to think that the current self custody solutions will make people feel safe enough. I would love to see the improvements that Op_Vault can bring to self custody brought to Bitcoin.
