It should be incumbent on pilots to know the effects of secondary controls...usually Lesson #2 in Basic training..

Speedbrakes being so close to the CP will not induce a big pitch moment in either direction.
They will kill quite a lot of lift, meaning they will cause the aircraft ROC diminish or even turn the other way all things equal, not what the pilots were looking for.
