I would think that this is counterproductive in terms of audio stability.
You had in parallel
- the audio flows for all channels (no matter whether in use or not) and
- the additional "high bandwidth" traffic of DURec files.
At the same time, the recording interface needs to stay stable as an audio device for Windows and audio applications (DAW, ...). Most likely this won't work satisfactorily, so this functionality makes no sense to me.
