I have already mentioned several times.
None of the aircraft ever changed its aerodynamics, wings, vertical stabilizer once their final prototype and official version have launched in the market. Hereafter almost decade in service, we are still playing with the designs and aerodynamics of the aircraft.
Mirages 3/5 variants do have slightly different vertical stabilizers, but the changes are not that drastic. Even Su-27 family has slightly different stabilizers up top, if we are going to nit-pick
The situation is exactly similar to when the team of developers doesn't even understand the importance of design and design trends. Without best and futuristic design (which you can see every single today's modern fighter) design, look and feel shape or you can say aesthetics are completely different from the JF17. There is a reason for that. It is not just aesthetics that members on this forum doesn't even understand. For them, I (he) is talking about the design which doesn't matter in this case. The aircraft is an aircraft, if JF shoot, kill, have better avionics, that's all for the aircraft.
For instance, if your aircraft having best avionics, engine, performance everything but the interface of HUD, Cockpit is too complex for the end-user, for the end customer, you product is redundant for them if it takes time for the end-user to understand the panels, gauges, touch, sensitivity of the touch system, WIMP, information available in the cockpit which helps user to play around at the time of intense battle. Here everyone asks me, hey are you, aero engineer. In front of them, I'm making my arguments based on shape/look lol. I guess for them, Russian, Americans and French are IDIOT who've spent millions and billions of dollars on the design industry to shape up these machines.
I responded to one question with two different images of JF17 V stab. In response to my question to him, what do you think if I'm an idiot and don't even know anything according to you... what do you think about this difference? why PAF has changed the design of Vertical stabilizer of dual seater? and why after the launch of version B, why again PAF re-do the shape and design of vertical stabilizer? he and many others running out of arguments, one says okay this issue which has to be answered by an expert we don't know why.
If you want to look into the answer to "WHY" you will easily get an idea of what "FLAW(s)" I'm talking about.
Does anyone have the answer? NO... one comes up with the funniest logic. They've changed the v-stab just to maintain the balance (weight) of the aircraft. He is not even sure why they've changed LOL.
If that's the case, give me an example of any other aircraft in the world whether light, dark, heavy, pink, blue which has two different versions and the engineering dept have changed the V-stab design of dual seater and the single-seater... F18? F16? F15? Mig? any?
BIG NO!
