I for one welcome the explicit blocks of email. They tell me simply what is wrong so I can (let people) fix things. What I really hate is the "possible spam detected"-like messages. I don't have time to check all 40 domains in the email and all IPs involved for those domains (and then usually not finding badness). I like to nitpick and find bad stuff, but that stretches it. Explicit blocks make my life easier.
So even if you weigh RBLs it would be nice to see the most important reason stated in the smtp reply. You could even change that behaviour given the reputation of the sender.

I think that in this day and age, this is true for *any* list - black-, white-, reputation- (yes, even ours). Whitelists can also have false positives - even pay for play ones, because while full-on spammers may not pay to be on a whitelist, or for reputation certification, etc...., organizations that are whitehat can experience personnel changes in their email and marketing departments, and an organization can go from blindingly white to a shade of grey overnight. Plus, even more now than ever, what one receiving system may think of as 'spam' another may think of as 'legitimate email our users just didn't know they wanted'. In fact, that's why we take pains to make a point that our lists are *not* whitelists - they are lists where receivers can get information about the specific practices of the senders - so, like Rob said - use them for scoring, not for outright blocking (well, accepting, in our case).
