Idk, this doesn't seem better to me, just a wordier way of saying the same thing haha. I think it's better to leave it as you had it, or just remove it altogether. IMO this NIP doesn't need to address achieving legal compliance - NIPS are about the semantic meaning of event data. So while I agree that relay owners SHOULD do this, it seems outside the scope of the spec. At least that's my opinion - don't take it too strongly. You are right, NIPs are all optional so it's not forcing anyone to do anything.
