While it's exciting to think about trading making a comeback, everything mentioned about this topic have merely been rumours because Rocket Racing is not very active and receives no more themed updates.Changes to the game code regarding trading is nothing new and doesn't have to mean anything, same with some teams resigning from the game. The "proof" you're showing here is nothing more than a photoshopped tweet used as a YT thumbnail in order to clickbait viewers and pickapixel, who apparently brought this topic up said himself that it's currently all hearsay and nothing concrete.
