Denel, you cannot feel about the issue the way the average Muslim feels. Some of the posters here from Pakistan are not properly Muslim, very often closet atheists, therefore don't share that same emotional attachment and denigrate the discourse to insults.
The problem highlighted with PAF has been rampant corruption and sometimes open treachery against the state. The common man views such people as traitors and the cause of them they blame on a class of people they call "babus" and "brown sahibs". Basically an english speaking upper class created by the British via the Macauley policy since the 1830s. You are basically chatting with Macauley's children here, not the real average Pakistani. This is why you can never fully understand why cooperation with Israel for Pakistan is not possible. It is perfectly possible for the kind of people demonstrated here because they aren't part of the group-feeling of Muslims and the average Pakistani.
Most of such people hate themselves and their own people, and if you look through their posts, you'll find it displayed. Most average Pakistanis blame the corruption and treachery on this class of people, as they have little religious morality to fall back on.
Be that as it may,
TVC does have a role much greater than just dog fighting. There are some technical papers available online, read a few, but can't find it right off the bat just now. These papers highlight:
1. Improved LO
2. Greater BVR-centric performance at high altitude combat patterns
3. Greater fuel efficiency in flight due to lower drag in certain very useful parameters.
And a whole bunch of other things that I can't remember of the top of my head.
PS: I seriously doubt JF-17 would get TVC. It is more likely though to find itself in the Azm project. Syed Yusuf here was suggesting an interesting configuration similar to your Carver project.
