Would be interesting to have a catalogue of endangered protocols/knowledge bases - similar to the endangered species list.
Bit of a tangent: just occurred to me that part of the story arc for the show 'Mr. Robot' is hackers trying to erase an entire knowledge base - the debt history of billions of people. The protagonists try to achieve this goal by peaceful means, but...okay I'm going to stop spoiling it's an awesome show check it out.
