cinema import camera and compositing mismatches
We should be able to read back in databases with static and phi-theta cameras and we occasionally allow that. However we should treat them specially because the 3d camera in a render view isn't a close match. We could use a dedicated view type or adapt the 2D camera for them. If we have a non-compositable spec A database that lacks depth information a dedicated view type makes more sense as we can't show anything else in it.
