Gmail's already implemented it.  I'm pretty sure Yahoo is also planning to.

Keep in mind that the list and user info have to be encoded in the
existing List-Unsubscribe header, and one-click just adds a fixed
List-Unsubscribe-Post header to tell the recipient that it can do a
POST for one click.  The encoded header makes regular unsub work
better too, since it knows what address to remove and needn't ask the
user.

Yes indeed.
