Anyone using Volz servos?

There’s a few posts from a couple of years ago about these servos but nothing recent.

Has anyone got first hand experience using the smaller Volz servos?
e.g. https://www.volz-servos.com/actuators/detail/da-15-n/

I see they support UAVcan V0 and RS-485 with useful telemetry. Curious to know if anyone has success with either of these protocols and ardupilot?

Am I right in thinking that UAVcan V0 is not the same as the natively supported Dronecan within ardupilot?
