OK, that's as it is for everyone I know, and it's already documented.

Is that just the known Audacity multi-channel limitation that to record
the channel you want, you have to record all of them? Or some other 
issue?

I can also change the system audio output slider (easier to get at). 

I think that behaviour is not terrible, but perhaps you should try other
apps that record loopback - I think Total Recorder does so?  

If the output slider cannot be made to do anything when recording,
can/should it be greyed out?

Actually for me the recording level is not a problem now, nor for most
people I've asked. 

The low recording level under WDM-KS when recording stereo mix 
seems much more of an issue.
