Funfact: about a year ago some semiconductor manufacturers wanted to standardize something similar: put JTAG on CAN bus. They explained it that way, that it would be a great benefit to debug ECUs via the on-board diagnostics port (ODBII) and may be later even over the internet. They tried it behind the automotive scene. But we managed to get many major OEMs on board to prevent that standardization effort. This would have been the greatest easter egg for all cars, it that would have been happened.
