Fair point, but the next paragraph says:-
"Pilots not qualified to fly in IMC shoul accept a RAS only where compliance with ARC advice permits the flight to be continued on VMC".
So, you can be IFR whilst simultaneously VFR - which is the get-out. In reality it primarily means flying quarantal rule. The same, I think, applies to Radar Control.
Actually I can't honestly recall ever using RAS outside of training (and not often then), I've always used FIS, RIS or Radar Control. The nature of my own flying never calls for RAS, and I can recall very few occasions when I've heard anybody else call for it either.
