I think an argument can be made that, while there were obviously multi-role tactical aircraft before Desert Storm, the draw down following it (and the Cold War) also created the brain drain from the de-specialization that went along with multi-role's ascendance. The Wild Weasel community for example, lost their EWOs and the AN/APR-47 in the F-4G for single seat vipers with HTS. Allied Force is a pretty good example of how this was not really optimal. The Tac Recce community didn't fair any better, their mission was more or less obliterated. The only vestige of this capability was the TARS pod, also for the F-16. This was and i think technically still is a mission that was more or less dumped on the guard since they had basically sun-downed the RF-4C mission and the block 25/30s that carry it were making their way to the ANG. The TARS system as you might recall was deployed in OIF but it's inadequacy was I feel pretty confidant stating, a major driver for the rapid acquisition of the MC-12Ws.
Of note as well is the TR-1A/U-2Rs (pretty sure they weren't the S yet) and RF-4Cs turned out to be WILDLY insufficient for theater requirements was back in ODS, so much so that we begged the Australians to send their RF-111Cs which did not happen. So, we didn't really have the juice to cover major combat ops then. Does the RQ-170 make up the difference since then? Not gonna speculate on here but i guess that's a lot of what it comes down to. However, the idea of have those sensors, but like updated in the cockpit, real time and in the link with dudes in the jet...seems like an idea worth revisiting.
