I should also add that there are at least two matrix spec change proposals flying around to add role based ACLs, and one of the main reasons for switching spaces to be built on rooms is that they will automatically inherit the ACL model when it lands :)

And neither of those two proposals have figured out how to solve the mess of the conflict resolution.

Solving conflict resolution should be doable - it's just that it's literally the most critical and important bit of the entire Matrix ecosystem, and any changes have to be done very deliberately and carefully, ideally with formal proofs that it's not going to break stuff. It's the equivalent of switching out Git's merge algorithm (https://github.com/git/git/blob/master/Documentation/technic...) or switching out for a new kernel scheduler implementation. Any bugs or thinkos there mean that the whole fabric falls apart, hence wanting to consider it separately to Spaces.
