More good questions. "I, the sender, want this to not be able to be validated after this date" is all well and good, but the sender's wishes go directly against the recipient's wishes, which are to have as many validated messages as possible.

That's not correct. The receiver's motivation is to defend itself. Validating messages a priori does not do that. If a sender through its own policy says "don't trust/honor/blame me this after this time", why should a receiver not honor that? That information only negatively
reflects on the message,  so a receiver should be happy to know.
