Corollary suggestion: mark the internal audio device as 'off' (as if
user had set 'off' in Configuration of pavucontrol) when jack takes
control of the audio device. More suitable to what has actually happened
then having an 'active' sink which doesn't accept audio, pausing
whatever streams happen to be playing to it at the time (and causing a
'hang' in the sound app, though I know that's an app bug in audio
handling). Right now I can just manually move the stream to the
module-jack-sink output and the app continues fine, but if the sink had
been marked 'off', this would have happened automatically I believe.

This second suggestion is more wish-list than anything, since I know its
not as simple as the first.
