On the contrary, it can be very practical, depending on how you want to do
it.

If you want to give your users a choice, assuming that you have some sort of
user account preferences website, it should be very easy to put a recipient
whitelist entry in the greylisting database for every user that would exempt
them, and let them opt in by selecting an option in their account prefs that
removes it.

Or, reengineer the code to pay attention to some other list (database,
flatfile, whatever) that controls if a user has greylisting enabled, and use
whatever mechanism you desire for controlling it.
