There's literally zero point in 3D TVC and 2D TVC only has marginal benefit for reducing drag, which has to be balanced against weight and cost. HMCS and HOBS/LOAL destroyed almost all point in TVC systems, not to mention the move to BVR and stealth.

Adding thrust vectoring to an existing engine and airplane would mean redesign of the engine structure, engine mounts, and fuselage structure to handle the additional structural load cases. Added weight and cost, along with the expense of structural analysis and test (static and durability) to verify structural integrity.

And then recalibrating the FCS to account for the shift in CoG.

Good point. It might also be necessary to add ballast to the nose area - more weight.
