The biggest fear I see from people is the idea of the back wheel floating, the front end locking up and/or locking up the rear when they are braking and downshifting.
This aren't cool feature or a problem with them bike. Smoothness on the brakes is just as vital as smoothnees of the throttle. It's the rider's inability to blip the throttle smoothly when they downshift and trying to drop down a couple gears really fast while braking hard. I had the same problem at the track.
Robert, I think as far as streetriding goes, its a question of safety margins. Granted, I'm terrible when it comes to braking hard into turns-- I flat out don't like the sense of almost out of control, the little nitpicker in the back of the brain that says "If you don't hit this, YER SCREWED!". In short, it limits your available options when your front end is compressed, you're already hard on the brakes, and suddenly you need MORE? Forget it, you're screwed-- dive into the corner and pray for the best.
Personally speaking, I think I went too far in the opposite direction, thinking that a good rider should NEVER use the brakes, that they are a sign of weakness and inability (which is hardly true-- just that some newer riders hammer those brakes unnecessarily

). No, on the street brakes have their place as a finesse tool. If you really need that hardcore braking power, you either seriously misjudged, or you got some bad, bad luck...
That said, I know for sure that corner entry and braking on the track is a big problem for me

I tiptoe into corners like a granney getting out of a slippery bathtub. I'll claim its a street riding habit

but still something I really have to work on.
