If the glideslope and VDP/EOD... are included in the approach installed in the FMS and come up automatically when the approach is selected, I believe most pilots would prefer to use it.
Manual entry of waypoints and altitude constraints while on the Initial Approach segment seems rather late for this kind of fancy work. While manual entry might have been done and crosschecked properly before beginning descent from cruise, if the approach gets changed in the terminal environment, dive and drive seems the less errorprone method in a high workload phase.
