Quite right.  MAPS also runs the very useful MAPS DUL that lists address
ranges used for dynamic dialups.  The RSS (the open relay thing) won't
even test addresses in the DUL.

The DUL is a very effective anti-spam filter with very few false
positives, since hardly anyone other than spammers sends mail directly
from dialups without relaying through their own ISP's mail server.  I
get the occasional whine from Linux users who think their sendmail
setup is so cool they don't want to dirty it with a smarthost line,
but they're easy to ignore.
