I think the AFCI is the last war. That is over, they almost work now. We should just use our experience with that to fix the problem of "the next new thing" getting jammed in the code before it is ready for the public, going forward. We are at version 3.1 or higher in the AFCI and it is just starting to return on the promise. We should not have been selling these at the point of a government gun during the testing process.
