Jussi's probably the best person to answer this, since the request traces
back to him.

But I can make up an example. Suppose I have a desktop environment with a
set of widgets on the screen, where each widget's audio stream is
spatialized to sound like it's coming from the widget's position on the
screen. Now suppose I have a media player widget that uses an internal
audio graph. It would make sense to offer a "pause" API for that widget (or
maybe all apps); that API would want Chris' behavior 1a.

That may be a bit far-fetched. Maybe there are less far-fetched use-cases;
maybe there aren't. The example of a game that pauses to switch to a menu
with its own sounds is close, but it can be handled with multiple
independent audio graphs since the menu and the game never need to be mixed
together with effects.
