Wow, the Jason Scott! While you're here, can you please answer two questions:

Does the Wayback Machine retain data excluded by new robots.txt rules? (In other words: If you change your policy in the future, can the change be retroactive?)

Why does archive.org keep this policy? It drastically limits what The Wayback Machine could be. I've searched quite a bit, but I haven't found a satisfying answer.[1]
