Hey Ryan! This is a great question for our Product Team to take a look at, but here's what I know: The preference center page is totally fine for the required unsubscribe option in the body of the message, but the list-unsubscribe header needs to be a true one-and-done unsubscribe option that happens seamlessly within the mailbox UI and doesn't require any additional user input. You can read more about it in RFC8058 if you're feeling especially nerdy. 🙂 Hope that helps a little!
summing up, can you have your unsubscribe link AND a change your preferences link? would that be OK?
