Well, in my experience, reverser systems, including indications, were extremely reliable
I don't doubt your experience but
just the the stuff going on in Lauda etal is enough to suggest that todays reverser system suffer from multiple false interlocks and warnings requiring the crew to manually retard the throttles before something goes tits up when they expected forward thrust only. we finally had to add even a third manual lock (not at the engine level) to accomodate all these clap-track sensor foul-ups
If we were to have tied all these interlocks into a FADEC I'm afraid we would have lost even more aircraft during the critical V1-V2 takeoff phase.
Sorry but we do depend on the pilots even today
