I agree it would have been better to put the key in the signature, but I thought the problem was that Cisco didn't provide clear license status of Jim's patent on that. I believe it's expired now. But I also see this patent https://patents.google.com/patent/US8090940B1/ which covers a signature that includes a copy of the original header and doesn't expire until 2027. That seems uncomfortably close to the header modification unwinding stuff.
