They cerainly should install it by default. They may ship if it if
they like to collect bugs.

Simply use pavucontrol. Use tunnels and right-click on each stream you
want to move to a different sink.

root *window* properties. But I wouldn't call that "canonical". There
are multiple ways to configure the server to use. The X11 root window
property stuff is just one way, but a very useful one. You can user
env vars, too...

Yes, that's why you should be using pavucontrol. It exposes that
functionality in the UI. Simply right click on a stream and there you go.
