Why is the maximum Integral disabled?

The line

AutoPID/AutoPID.cpp

Line 61 in fea6b99

//_integral = constrain(_integral, _outputMin/_Ki, _outputMax/_Ki);

which contains the Integrator max is disabled. I'm curious why? Is there some inherent problem I'm not aware of? Furthermore, would you accept a PR for a function like setMaxIntegrator (100) ?
