We have datasets that aggregate datasets of features.  If I want a geospatial 
search to work at the catalogue level (ie harvested from multiple 
institutions), then it needs to work on the aggregated bounding box. (I'm 
answering your question wrt to the need for overall bounding boxes, not wrt 
to why bounding polygons coz I don't think you were asking that).
