I think this might be not understood yet, but JACK 2 *does* allows this.

You can switch devices (or any jack settings) during runtime, without 
having to stop JACK.
This is called "switch master".

Because of this the buffer-size *and sample-rate* can change while JACK2 
is running.
In which case the respective callbacks are called.
