Exactly. Ancestors only. Inflexible. Presumably you would occasionally want elements other than ancestors to be affected by the media state.

And yes, you would still need scripting to build a full-blown media controller, but with these pseudo-classes, you could totally get away with just CSS to skin existing controls.

I think there is a whiff off adding features for the sake of adding features here. I think you should at least get some traction in whatwg first.

I don't really feel very strongly about this either way. Just asking the potential reviewers to consider if this is really worth doing.
