The Panigale's engine/handling characteristics mostly remove the need for the rear brake.
Under EBC 3, there's still quite a bit of engine braking. Unless you're at the limit of trailbraking in a tight corner where you'd benefit from some rear brake to tighten your line, you don't need the rear brake. It still has its use however when you or the guy next to you makes an error at the track.
There's not a lot of engine torque so the 959, similar to other middleweights, is more considered a corner speed bike. Unless you ride it with a point and shoot riding style (with TCS off), you don't really run into problems with wheelies either.
