There are several open questions at the moment regarding where transforms fit into the heuristic system.

• Do they only impact "Spatial" views or can they be used to split content in different kinds of views.
• Is there a mechanism to "query" entities up to the next transform?
• Is there actually a difference between a "DisconnectedSpace" and a Null "SpatialTransform?"
• Can a pinhole transform be converted to a rigid transform or does it create a permanent topological disconnect between 2d and 3d spaces.
• Can 3D content be added to a 2D space without a transform?

This would improve clarity for users in issues like:
