if it existed, it could be beneficial if it worked the same way as the electric mid gearbox for the same reasons since it’s roughly the same thing in a different spot. It feels like if you go that far it might as well be a motor since some types of motor can be rotational position aware for firmware use which I’m pretty sure is how it works on the pinion electric gearbox.
Why only derailleur bikes? Doesn’t seem any better with an internal hub either.
It can make more sense on an ebike though!
