the LTMA will be as free from gliders as it will from illegally intruding GA aircraft of other kinds
Indeed - the difference is that not only GA planes are normally visible on radar even with the XP off (gliders usually aren't, it seems to me when flying under a RIS) but GA will have to carry and use a XP before long.
The question is whether having visually poorly visible and electronically invisible aircraft around is a good thing. On the face of it, no, but in reality there are few collisions between gliders and non-gliders, so it seems to work.
