I've implemented AA for the "status" query in 8.2. It would give the
comma separated list without the space, behaving the same as the...
other query (what was it again? albums?). This fixed the Default web UI.
And using AA instead of A should be backwards compatible from your POV,
as older versions would simply see that "A" was being used.

Thanks. I've updated Material, for 2.2.0, to take advantage of this.
