And i'll bet most dont have an ECU capable of monitoring so many inputs and good enough error strategies to do anything effective about it if a fault does occur.
Thats sort of true, the trouble is that AFR and fuel pressure are post events, reactive. So the pump can fail/go weak and you can have a slight delay before you see an AFR or pressure change. By then the change happens very quickly and you have little or no time to reduce boost etcetc. Being able to see a pump fail or begin to fail as it happens with no delay would be a faster way to avoid terminal failure.
That being said, ultimately AFR, EGT and fuel pressure would still give you very useful info, having just one of those gauges in your car is more than most people have any way.... It always makes me laugh when you see a million gauges in a car, clock, volts, water temp, maybe an oil pressure gauge but rarely something as instantly useful as EGT or AFR..... Plus an AFR gauge has loads of flashing lights so you would think Kevin would love it?
