Interesting, haven't thought about that from your pov but I did consider how awful Pkarr is for an organisation even if it wasn't too long because of this issue. To be fair, not even Blockchain based key management is fool proof, but because the smart contract can mimic anything, a team can even use their control of a domain (and DNSSEC) to recover a Mlkut name... But even then, none of this comes for free you have to develop it. But Gnosis Safe is widely used by crypto companies to manage funds, so I assume it is adequate.
