We now have a checkbox next to the map loading icon, to desactivate the map.  
The problem I see is when one such checkbox is un-checked there are still some instances where the bitmap is loaded, and sometimes used in the render.  
We can see in V-Ray’s info window that the bitmaps are still loaded at rendertime, they are showing in Rhino’s “rendered viewport view” and they sometimes show in a render, maybe when they are in external blocks.
