IMHO, it should take a value.

This value would reduce the volume as it is done for WKPageSetMediaVolume but it would be recoverable after with UnDimm.

We need to consider this, yes. If a set is made while the volume is dimmed, we need to deal with it somehow, either by failing or ignoring the set or by failing/ignoring the undimm.
