Yeah, 'cos most zooms, apart from some point and shoot, are manually operated only, so therefore there would be no controller circuit.
There are a couple of Panasonic m43 power zoom lenses. I got the 14-42pz with my first m43 camera, and it was ok but not great, but it was tiny when powered off. Ultimately it was replaced by a better lens and I sold it last year with the camera. There was also a 45-175pz that I have no experience with, but I think the general opinion from those who have used it is that if you don’t need the power zoom there are better options. The zoom could be controlled from a leaver on the lens, remotely from the Panasonic app on a phone, or there were a couple of bodies that also had a zoom lever on them. I don’t think they were a market success because they didn’t stay around for long.
