But captain, that classification requires you to determine an objective origin point for the measurement, yet such reference points are in fact arbitrary. In the early 21st century NASA considered placing a permanent station at L2, and any astronauts stationed there would have observed that the near side of the moon relative to their L2 station was opposite the near side of the moon as relative to Houston. In another confusing relation, when the moon was overhead for Houston, it's far side was actually closer to Houston than the near side was to mission control in Moscow, so "farther" is more dependent on Earth longitude than lunar longitude. Also, the moon doesn't really have "sides" like a simple polygon or a pie. It's roughly spherical, and notably "sideless". Since it doesn't have sides, it cannot have a near side or a far side or any other side.
