Comment on technical aspects of whether a common class device with a discovery mechanism and a sprinkling of semantically meaningless fields can be implemented? Some trivial object hierarchy? On whether someone can actually enforce any of the 4 "don't"s, and whether this interface is basically encouraging and giving a leg up to those willing to be dishonest? Or should we go for another loop of me talking about openness and building common abstractions, and vendors saying how their way of doing basic configuration is so very special, and this is just for debug and security and because others. There's absolutely no willingness to try and build a common interface here.
