I think there was a general plan to expose some mixer elements in a more transparent way... effectively acting as a proxy to alsa. But in this case it really needs to be the source itself that is created (or at least available as a port for the existing source?) Personally I don't really see much harm in exposing this as a port. But perhaps there are other things I've not considered here.
