Literally is the definition of continuity error, if future outfits are worn in past periods. Would a spiderman prequel where Tom Holland has the nanotech spidersuit be a continuity error if it was set prior to Homecoming? Yeah fuck right off with that retardation. You set off this derail with your usual combination of stubborn retardation and goal post shifting.
And I honestly don't really give a shit about the suit, but its part of a broader issue (highlighted in many other ways) of how the new writers clearly did not study the source material at all. See also Nu Trek for this kind of faggotry. They were so busy trying to cram THE MESSAGE into a show they never bothered to make sure their shit lined up with exiting continuity. The suit is just one minor part of the whole problem.
Faggot.
