Is there an obvious reason why `@` is not allowed in the local part of a `nip05` key? It would be nice to have proxied names like `alex@gleasonator.com@mostr.pub` instead of `alex_at_gleasonator.com@mostr.pub`. Assuming it's not allowed in the domain part, there should be no ambiguity in how to look that up.
