Normally, with test data in hand I would agree. However the CAN bus as implemented by the Jagaurs sort of demonstrated how what you get that uses a CAN bus can greatly impact the risk of CAN bus. There were a lot of people that had Jaguar issues and when those were the only ESC with CAN one gets one problem leading to another.
I am not being overly critical of the Jaguar, but FRC11 finally decided to stop fielding them and they now are in a box in my one shop as a result. They were too complex to debug in the 6 week season, changed manufacturer too many times to get fixes and we had some design issues that the Jaguars took heat for. There were some teams that stood out as Jaguar success stories and credit goes where it was well deserved, but it was not the best investment of FRC11 time and resources.
I look at branches and star in a similar way. It would seem to be an interesting rabbit hole. The recommended design does work so why invest in the alternative?
