ADSP was a preview of everything that is bad about DMARC. I made the strictest level "discardable", to make it clear that it's for unimportant mail. My co-authors hated that but had to admit it was correct. I also predicted that most of the people who published ADSP policies would have no idea what they were doing, which turned out to be correct. Around the time it was published, some eager beaver added ADSP to his mail server and for some reason decided "discardable" meant to reject the message. So of course IETF mailing lists broke the DKIM sigatures, he rejected all the discardable messages and bounced himself off a bunch of lists. Once people realized what had happened, there was no further interest in ADSP that I can recall.
