Aye. The Docking Port is something that was to allow ships to dock without actually going inside that entity (ie capital docking with a space station), but no-one has gotten around to coding it. Probably because it wouldn't make that much difference, since presumably the ship would still be outside the entity and so still shootable, plus anyone can hop between ships in the same grid, which is what docking ports may have a allwed.
Well, the purpose of a docking port would have been to force ships to either land in another ship and enter it that way, or use its docking port. In theory, wouldn't both entities require a docking port?
This would stop being able to hop from a fighter to a YT-1300 in the middle of space. Which does make sense.
