You are wrong, it is not twice as much work, not even near.  Worst case is that
you get greylisted once per recipient/sender pair, that's it.

With  milter-gris I use the option of only greylisting dynamic IPs and those
that don't have a valid reverse.

And bottom line: about 90% of the spam just disappeared.
