At least in certain joint configurations, dragging a component may cause other components to jump far out in space. If that happens, working on the model may become impossible as at least some display drivers cannot handle geometries with a very wide span of dimensions (e.g. details on millimeter level while model extents span over one kilometer).
There should at least be a warning if a component is about to move very far out compared to the rest of the model. In addition as a means to removing problems with outlying components, there could be an easy way of selecting or removing components outside a given distance from the origin.
