It's because it was our very own Powered Convoy "Randy" himself who chose to give "Thundercracker-with-Thrust-wings" the new identity of Nacelle for Fun Pub, not Hasbro proper.It's funny that while Thundercracker-with-Thrust-wings got a new identity as part of Hasbro's "Let's name every. single. use. of the model" phase in the mid-2010s (being named after an Exodus Seeker likely helped), I haven't seen the same treatment for Skywarp-with-Dirge-wings or "Not-Bumblebee-Movie-Blitzwing".
