They did this a long time in the past (See: Rocket League Rocket Labs) and it was near-universally disliked.
The complication when it comes to adding new features is that Rocket League is built on top of a bespoke scripting engine that was discontinued after Unreal Engine 3, so they have to fully recreate RL in UE5. Because of this they don't want to put any additional resources into new features for UE3 since it's wasted effort once the game transitions to the new engine.
