To quote your own words:

>So here's where I'm a hard-ass and maybe even worse than google's rules. If I see the RFC8058 unsubscribe link, it is too late. I only notice that link after I've decided to mark your email as "spam" and google asks if I'm sure, or if I merely want to unsubscribe.

The way I read it, this is an unwinnable situation. We must supply this link, in order to comply with Google's rules. If you see this link, it's too late. You're making it as spam. Because I may run javascript on your computer.

Having re-read it, it sounds instead like: you're likely mark it as spam before you get to this link (even though the web interface surfaces the unsubscribe button right in the list of emails -- but you don't use that interface).

Well, I guess there is a narrow path to "victory": mention that it may have been someone else who signed up, then if you see the unsubscribe link, you click it, then I'm supposed to say "thank you" and not serve any javascript. Anything else, and you click SPAM. Or maybe you already did.
