Actually, IFR is Instrument Flight Rules, meaning that you have no visual way of flying without the assistance of ATC. Since many want to fly quads BVLS, it can't be VFR or IFR since they have no way of seeing anything beyond what is shown a view screen. By definition, since they can't see out of the quad without a camera, it can't be VFR and, since there are no instruments (compass, artificial horizon, altimeter, etc), it can't be called IFR. To take it one step further, to fly any aircraft IFR, you have to have a pilot's license with an IFR endorsement, something I know no drone flyer is going to have
