It would certainly make it easier to deal with grumpy gmail users,
since gmail does not provide junk button feedback.

The disadvantage is that every recipient needs to get a separate copy
of each message, because the list and user info has to be encoded in
the list-unsubscribe URL.  That's been standard in commercial e-mail
for a decade, but a lot of discussion list operators still imagine
that it's too slow.
