Which would probably help with the fact that the supposed "nozzles" aren't anywhere near the obvious trust line...
But if we accept the TNG Tech Manual idea that the motion is the result of acceleration of propellant from the nozzles, and
some sort of inertial manipulation thereof, then we might have a win-win scenario. Perhaps the momentum that the ship gets from this can be applied in whichever direction, by "field magic", but the momentum has to be created first, and this requires allowing the propellant to spray out across sufficiently many meters of free space in traditional rocket fashion? And this is why, out of all the possible arbitrary placements for the nozzles, they are placed where they also work as traditional rockets.
