Yes, this design seems more appropriate than adding parallel class
hierarchy... Occam's razor principle...

Hm... I used this approach with previous desing: I don't assing
InteractingGeometry with virtual facets (utils.facet have a
noInteractingGeometry flag so far). But, seems, the collider would to
give a errors if body  have not a bounding volume... or not?

So, can I to add isVirtualBody flag to InteractionGeometry and
 to modify accordingly InteractionGeometryMetaEngine?
