Hydraulic coupling is extremely lossy and should be avoided whenever possible. A turbo can be transmitting 40hp in bigger engines, and for most applications at least 10.
Mercedes did not split their turbo in half, they kept the shaft because boost is constantly being used so it's better to have more efficiency under boost than less wasted power off boost. On a road car it makes more sense to have a fully electric system because a road car is barely ever on full throttle, but the electrical system needs to be super beefy to transmit that kind of power and so it's probably better to just compromise somewhere and keep a mechanical connection.
