If Apple were to add new APIs, it might be possible to use personal cloud storage (NAS, Decentralized Web Nodes, etc.) with the same UX as iCloud with E2EE.

Scale matters. Police don't have the time to go through everyone's computers. It is much easier to scan everyone's conversations, notes, or photos. Cloud storage invites this kind of mass surveillance by being high-value targets with little capacity to resist.
Ah, so in the UK or China this could go through a proxy that steals all the keys.

For all the checks you put on people who can access this stuff the temptation is too big - just look at the intelligence analysts using systems to stalk Exs etc.
For any system like this to exist you must ask yourself if you would be happy with the worst person you know having a job where they have access to it.
