the pressurised fluid does not come about without cost of weight, bulk, and complexity ?
or are these already charged to the gearbox's account so we act as though they were free
the electromechanical way would be straightforward (assuming we only want vlim length proportionate to rpm)
the car is already swimming with electricity
are the throttles actuated hydraulically ? - assuming they have throttles
(given the topic was apparently not dismissed days ago)
Could be like cam phasing or VANOS/VTEC/whatever variable lift doohickey, and just work off the engine oiling system. It's not a big ask from the actuators, nothing a 100psi positive displacement pump can't handle.
If you want to get F1 technical about it, run the pump off the MGU-K, then you have a secondary energy storage through the oil pumps, the tank itself can function as an accumulator, then you can feed energy back to the MGU-K, or to the accumulator and with the free path to the ERS via the MGU-H, you have the main ERS cells and a hydraulic super capacitor to supplement the MGU-K(your oil system). This is nice because it lets you incorporate the transmission hydraulic system into your capacitor, so you can charge it by shifting. Hell you can even charge your oil capacitor via the drivetrain in excess of the 120kW limit as it only pertains to the MGU-K(although you'd only be able to send to the MGU-K at 120kW max), of course being a capacitor your charge is very limited, particularly by the oil capacity.
According to this it's allowed.
It could also serve to take some of the shock loading off the MGU-K.
