Realistically, reactionless or not, Maneuver Drives would be much more effective if they were separated into partial units and put at every extreme of the ship away from the center of mass; better leverage there. And just inboard of the Maneuver Drive units would be the sensor units, similarly “leveraging” the improved perspective that having its units mounted at the extremes provides. A ship would be much more likely to be “pulled” from the front and the sides than “pushed” from the back, unless it’s just some massive freighter or “ship-of-the-line”, for which turning performance is less important for one reason or another.
Maybe there's a core piece of the M-Drive that's way more expensive then the rest and so breaking it up into a whole bunch of little pieces would make the drive ridiculously expensive.
Maybe multiple M-Drives interfere with each other, so you actually have to use gas jets for turning.
Maybe the single drive actually generates a field that you can modulate to "push" on specific parts of the ship as you choose, thus allowing the single drive to be just as effective as multiple drives.
Maybe M-Drives do 'pull' and we've just been looking at the ships backwards this whole time!
With no real life analogue for a reactionless drive, and nothing solidly defined in the existing rules (as far as I know), we can pretty much justify it however we want, and thus, at least as far as M-Drives, there's not a solid "function" for form to follow.
