With correctly configured redundancy strategies there is no reason that they should be dismissed
Might open up a few more options for you

Yes Will im aware & Mark has already said he can use the ECU to detect problems so its really just belt & braces. I have a pedal that is 4 wire that looks like it may be suitable & if the couple of 6 wire im trying cant be fitted easily I will go with the 4 wire
