This point I will grant you, however I would think you would want to consider using bevel gears instead of worm gears. While back-drive resistance is nice, worm-gear efficiency can be as low as 50%, compared to bevel and/or spur gear efficiency of 93%-98%. Back-drive resistance can always be accomplished with brake-mode on your speed controllers.
