By new vehicle types I mean adding new categories such as 'Base' or 'Ship'. What you're talking about is adding new ships.

The game already allows you to create new vehicle types, but they all end up with unit behaviour( i.e. they stack in system view, etc.), unfortunately.

As I mentioned, the biggest advantage of this would be that you could simply put your new vehicle type in the 'Vehicle Types Allowed' field in components.txt to easily restrict weapons/components to certain vehicles without using mounts or other complex formulas.
