Yeah I agree. The complexity and subsequent risk of multi-sig is why I remain single sig with a passphrase and focus on an air-tight no counter-party risk key storage schematic. But for inheritance purpose it’s not great bc it’s so secure and depends on me and me alone. Not willing to write out instructions on how to destroy my security model.

I think OP_Vault can an excellent solution that will allow for new and better custody / inheritance solutions. Maybe one of the last BIPs Bitcoin needs…
