Any fault that cuts the power path to the radio, cuts the power to the radio. The fuse isn't going to matter, blown or un-blown it's already too late, the match is pretty much over.
Protection cannot do anything about a complete loss of power. It can only help prevent things that are bad from getting much, much worse.
Short protection has been greatly increased, so CTRE/NI have isolated faults to pretty much where they occur and not neighboring systems. roboRIO DIO shorts won't also take out the PWMs, but yea, if our wiring is bad, then there is no genie that will fix that other than our own electrical sub-team.
Beta teams will test the shorts that seem reasonable, so if you have ideas let all of us know. It might not be something we've thought of to test.
