I think it's fine to make any in-body link a two step to unsub - click to confirm - to avoid bot clicks and false positive unsubs. I'd not go crazy beyond that. CAN-SPAM disallows putting a login in front of the unsub process. Does that apply to your mailing list/groups mail? Not clear to me, but I wouldn't want to find out. You'll definitely get people complaining that it violates the law. Will moving to "two click" on any in-body unsub link affect you negatively? No, not really. You'll be fine. And it's compliant with Yahoo/Google. They're only mandating one-click as in "one click post" via the list-unsub headers as you've already suggested that you comply with. It is not uncommon to use the same URL in both the list-iunsub header and the body of the email. If somebody visits the URL (not post), show a confirm step. If somebody POSTS to the URL, then it's a list-unsub from a mailbox provider, and unsub without a confirm step. Here's more detail on list-unsub/list-unsub post if you need it: https://www.spamresource.com/2023/12/bonus-webinar-crash-course-on-list.html But I rather suspect you've pretty much got it covered.
