There certainly may be use-cases where media in one (or both) directions are
inactive or DTX-muted for considerable periods of time - remember, many of
the use-cases (and unknown interesting future uses) aren't "phone calls".

In particular, I have some interesting use-cases bubbling in the back of my
brain where the data channel remains open at low/no activity and the media
channels are inactive or non-existant for long periods, or where data traffic
predominates and media are often inactive.
