equipment_grid for non-armor items?

[Pyro93735]

For a mod I've been planning I've wanted to give a module grid like power armor has to other items, such as tanks or turrets; is this something that is possible, or is equipment_grid strictly a member of the "armor" type? Simply adding a definition for equipment_grid to a tank definition doesn't seem to do it.

The equipment_grid property is only consumed and used by the armor item type.

None of the other C++ classes implement equipment grids and none of the logic anywhere else on the C++ code accounts for a possible equipment grid.
