'Twas brillig, and Tsai Yu-Chin at 20/11/10 04:00 did gyre and gimble:

That's the theory and it seems to work fine in pavucontrol... but I'd
have to run a little test application to see if it's misbehaving in
other ways.

Both. On the "Playback" tab, the VU Meters only show the current stream.
On the "Output Devices" tab, the VU Meters show *everything* outputting
on that sink, so the different use cases cover the two different modes
of operation.
