I seem to recall reading about something similar regarding field testing of new gear for soldiers.
The generals and sales goons would come up with all kinds of "would it not be useful if they had XYZ on their helmet". but once given field trials the feedback was that while it was nice to have, it made said helmets heavy, leading to neck strain and problems with simply looking around.
