You have said,
Wouldn't you rather be vectoring the 74 in E with all operating mode "C'"s rather than with an ID'd target in "C" with unidentified primary target (that could be in C you never know) in "G"????
and
I'd much rather traffic advisories in E on unknown VFR's rather than being an IFR Pilot in G without TCAS on descent heading at 200KTS toward a 4 seat 120KT VFR with no transponder coming the other way.
It is the mandatory transponder requirement of the NAS changes that gives the safety margins you are alluding to not the airspace reclassifications.
Whilst acknowledging that both the changes came in with NAS, they should not be seen as a package. There is no reason the two elements cannot be decoupled.
