Incubus, sorry I don't know how to apply a quote. The Tutor mid-airs were upper air and the recommendation would mitigate the risk of 'See and avoid'. I have been Duty Instructor at an A/G RAF Airfield VGS when the occasional Tutor came in. The made all the right calls, helping everyone's situational awareness and, after a couple of touch and goes, flew safely away - all without ATC. I think you touch on the issue behind cadet non-flying, mentioned early in this thread, the worry of the next cadet to be lost enacting Haddon-Cave's threat of safety responsibility being removed from the military.
