Have you ever been in a serious accident or a near miss? I promise you if it's very quick and violent, you will grab both levers instinctively and not be thinking "oh, little front wheel lock...better lighten a bit."
If you actually make contact, hey, probably wouldn't have mattered. But the times when you can be lucky, front ABS will save you lots of money and painful debriding, or worse. For reference, I've been in many bike accidents and I'm very grateful for the standardization of ABS.
Seriously, I keep my ABS on 1 in Sport mode and do full force stops from time to time. The ABS activation point is no where near anything that would upset a mid-corner line. If you're worried about the rear brake...if you're finding the ABS point on this you're doing it wrong.
Comparing race cars/bikes has no merit if you are riding on the street. In a car, you lock em up and can probably save it by letting off the pedal. On a bike, bye-bye front tire under most circumstances - you're now scraping down the road. Sorry, I was a very dumb kid and after many years of analysis, ABS would have saved me from 75% of my mishaps.
