Chicken leg
I tend to agree -re ISTAR. With the formation of DE&S, MoD had the opportunity to move MRA4 into DG ISTAR, along with the likes of UAVs, Sensors and Nav, Air Command & Control, ASTOR. But they didn't, placing it in DG Air Support along with FSTA, A400, C17 etc (and Nimrod, which is a separate IPT, which always struck me as peculiar). To me, that shows the original role has not changed in the eyes of MoD. If ISTAR has become a de facto primary role, I'd allocate responsibility accordingly.
You say 2009 will be a decade. I recall N2000/RMPA/MRA4 originating long before 1999. I read the Cardinal Points Spec for the avionics in 93 and it was old then. Assume you mean a decade LATE!!!
