I'm not sure if I would agree with that. The most recent Jetfire is the only official figure that really seems to give much attention to the animation model. The few before that mostly seemed to be aiming for "Valkyrie knockoff", though they wound up missing the mark because Hasbro was afraid of rousing Bandai's legal wrath.
What amazes me is that no third-party companies have tried to make a toy-based Jetfire. It's not like they have any qualms about "borrowing" other companies' character designs...
Your Lego version is pretty damned cool, though!
