Did I say anything wrong about JHMCS or its ability to target weapons ?
What I said is that the situational awareness is more inside a HMDS.
F-35 has HMDS so would EF2K and Rafale.
Then you must also know that HMDS are going through some technical issues and is sometime away from operationalization.

Fancy futuristic JSF helmet still not working
Schools are already in place to train fresh F-35 pilots now that the aircraft are inching closer to actual service duty. However, one thing that was still questionable was the wild looking helmet that is intended to give the pilot a 360-degree view around the aircraft.
The problem is that the high-tech helmet that the F-35 program needs is having some significant issues with performance. Specifically, the maker of the JSF helmet, Vision Systems International, has been unable to get high quality images displayed on the pilot’s visor.
Since the availability of that fancy helmet is questionable, a contract to create another helmet with less technology crammed in has been granted to BAE Systems.
BAE is using a version of the helmet that Eurofighter Typhoon pilots use. The Typhoon display that would be in the helmet is being removed and it is being replaced with a set of night vision goggles and a single eyepiece showing the heads-up display HUD.
"BAE Systems Electronic Systems is proud to be a part of the Lockheed Martin team for the F-35 HMD,” said Jim Garceau, vice president and general manager of defense avionics for BAE Systems. “The NVG HMD will enable all aspects of flight operations and it allows us to build on our long history of successful development programs with Lockheed Martin on the F-35,
F-16 and F-22 programs.”
The helmet will also incorporate the BAE Q-sight and head tracking technology to help with precise weapons delivery. The modular design also allows an upgrade path for pilots to binocular visor-projected displays, alternate image sources, and night vision.
The helmet can also be easily modified if it becomes the main helmet for the F-35.

So, if it is not ready for F-35 yet, then having it in other jets is highly less probable in near future.
