Not at all Skoorb. Better brakes provide better modulation of stopping power without locking up. That's the whole idea of them. Even the crappiest of brakes can lock up, true. But they'll go straight from poor stopping power to locking up with nothing in between and little ability to control the difference. Getting more stopping power before lock up and a better ability to control that stopping power is why people upgrade their brake systems.
And then there are the advantages of reduced fade, etc.
Really though that's of negligible consquence to somebody with ABS who takes their car only on the road. I know some people hate ABS, and sometimes they probably hate it just so thay have an excuse to use a big brake kit

I read a nice long thing on how on many cars getting big brake kits, it's buggaring up ABS, because those sensors are finely tuned to an approximate braking power, and larger/heavier/lighter, etc. wheels can also change things. Problems are especially accute when somebody slaps on a high grip kit on the front and forgets about the back.
