Since we're going for efficiency, why go through the work of sending the food all the way through the mouth and the esophagus? Just have a hatch in the abdomen with the internal blender there next to the stomach. That saves room in the face for the vox implant and other implants that are more conveniently located in the head.
because power armor. you may not want to get undressed to eat, but taking your helmet off is easy. getting to the torso under whatever armor you have is both socially impolite, as well as tactically inadvisable. the head is more often already exposed, and can turn in various directions. also, would you want such a large hole in your subdermal armor over the torso?
also, remember that cybernetic senses specifically mention taste, and such sensors are most often located in the head. a good cyber-tongue would probably include some type of chemical analysis sensor. once you overcome the weakness of flesh, such sensors can be quite useful for finding poison.
also, at the end of the day, you want to be able to vomit. its a basic defense of the body against poisons by ejecting them from your system. now, how many fun bionics do you think we could hook up to that sort of thing?
. Which sucks, because now I have to find a new main weapon for my adept. Before, it was all "I stab the cultist with my rapier wit for 1d10+Int Bonus"....
