That's not what the F35 does. It is a strike fighter. It is meant to stealthily penetrate enemy airspace and strike targets, as well as survive air combat after its strikes make it abundantly clear that enemy airspace has been penetrated.

Airborne Observation and control is a job handled by AWACS and JSTARS. While an argument could certainly be made for a stealth JSTARS, that's not what the F35 was intended to be, nor what it is optimized for. JSTARS planes should be long endurance planes, not super maneuverable supersonic VTOL jets. A stealth JSTARS would resemble the B2, not the F22.

The F35 does have an impressive set of sensors and communications abilities, but that's simply a consequence of being a more recently developed aircraft. It's really not too hard to appear impressive when your competition was designed to use core memory. A purpose built drone controller would put it to shame however.
