This idea has been suggested before and I really like it, and actually
would like to make it the default. I think there is a bug open about
this, and this will come, and is probably even easy to write.

I think the fact that somebody plugged in a device is sign enough that
he wants to use that. Also, if we eventually get analog jack sensing,
and automatically switch output ports to that jack of a sound card
something is plugged into, it would only be systematic if we did the
same if someone plugs in an audio device in the usb port, if you see
the analogy.

So, yes, I like this, I want this in PA. As a
module. Natively. Enabled by default. Patches welcome, and if noone
comes up with any I will implement this myself eventually.
