The argument for greylisting is apparently no longer - and if

So all Mr. Bad Guy needs to do now is realise the significant
uptake of greylisting for this one purpose, and never spam
any host that seems to accept all initial transactions. They
can do this simply by not entering the DATA state. And if
that's used as metric, by sharing data amongst themselves as
to the exact purpose of non-greylisting hosts.
First, your subject line appears to be wrong to me: "everyone"
other than honeypots do not greylist.
Second, if I correctly understand what you are proposing above
(and it is possible that I do not), why do you believe that the
spammers will cooperate in behaving the way you want/ expect?
They have about zero incentive to go to extra effort to not send
mail to particular addresses unless doing so will net them a
_huge_ (think severals orders of magnitude) increase in the
number of messages that get delivered.
