Yeah, pretty much everyone can benefit from a high-level grasp of phase margin and gain margin. Even in contexts where exact calculations are impossible, it's important to remember that cranking the gain too high turns your amplifier into an oscillator and that lengthening the feedback cycle reduces the gain ceiling above which this happens.
Typically, I find that people have an intuitive understanding of the possibility of overshoot but not of oscillation and almost never of the connection between feedback lag and overshoot/oscillation.
