They could be used to compute the aspect ratio, but they also could be
used to compute other stuff, so they're "broken" anyway if interpreted
as a per-camera value.

Also, if you develop a scene using a grid camera, you presumably know
what grid size you're using, so you can apply correction factors to
account for the mismatch between camera aspect ratio and image aspect ratio.
