I have one. A 1992 Performance Parabola touring bike with 135mm hybrid wheels, and hybrid derailleurs. Even the drop bars say "hybrid". But it has dual pivot side pull brakes, 170 mm cranks, bar-end shifters, and front & rear threaded rack mounts. It is a bit heavy, but it rides nice, at least unloaded. I would like to try it on a gravel road.
