I guess if we use message-id, then a signed message from the mailserver with the message id would do. But signed messages still usually contain a hash of the thing they sign, no?

Using message-id's for threading has literally worked for decades when the clients supports the relevant headers. It's not the message-id that is the problem, but lack of support for the headers carrying them.
