As per my tests, it treats them equally indifferently - when I click the "Move to spam" button, it just moves them without any additional questions, unfortunately. Also, I don't see any smart "Unsubscribe" button in my Gmail UI. Perhaps this is because I'm not a heavy sender on this mailing list... On the other hand, Yahoo (I know that friends don't let friends use it) offers an unsubscribe option even without the RFC 8058 headers, and it sends a valid unsubscribe request by email to the mailing list "leave" address when you click it. However, I'm going to extend my tests to check how Google Postmaster Tools v2 treats traffic from the particular server with and without RFC 8058 headers. Probably the former will be rendered as "healthier". I'll share the results in this list.
