So you're saying that the people in Red Bull are such huge technology enthusiasts, that they invest money and time in a system just for the sake of constructing it, even though they won't use it to gain an advantage in a race (cause they know that would've been illegal)?
I know that having a penis doesn't automatically make you a rapist, but in F1 nothing gets developed without at least an intention of using it.
It's perfectly possible that they only did it for the purpose of easier maintenance. That aspect of technology might not get as much attention from the fans and the media as, say, aerodynamics, but that doesn't mean it's redundant. If the mechanics are able to set up the car more easily, there's more time for testing it/they can focus their attention on more important things.
And even if that's not the case: As long as you only have but aren't using an illegal system, you aren't actually breaking the rules - the B194 is the best example for that
