I don't know how you'd go about automating that.But as far as your point about spam vectors it is surely just as true about ARC, right? at least with recovering the original text i have the ability to remove all of the transforms and deliver the original text. ARC not so much. it's all or nothing on the trust front. But I really think the key thing about all of this is figuring out what defines success. That is the most important thing by far.I think ARC, like PSD, is meant to run for a while and see what we've learned from it. Maybe it's the silver bullet, or maybe it's ineffective complexity. That should be part of the experiment's definition; Section 11 of the ARC RFC does try to capture all of that.
Btw, what is PSD? Mike
