I was thinking about audio CD only (44.1kHz). When dealing with
higher sample rates, the encoder should probably try to go higher if
it is really needed, but even then I doubt that it would go much
higher above 20kHz. The benefit of higher sample rates is mostly in
increased resolution, not bandwidth.

Well the point could be is that some people seem to worry too much about
bandwidth and not about the quality of what has been encoded. :)
