This is very true! The Civet Arrival into KLAX is a classic example. The ILS G/S to RWY 10 in KATL will lead you below published altitudes beyond 10-12nm. The deal, typically, is that the published altitudes will keep a turbojet above the Class B floor or some type of VFR corridor. If you dip below the published altitudes and fly below the Class B airspace you'll get int trouble. It's happened, apparently to some crews at my company (we get quarterly reports of these things).
