there are cases where the user agent will be unable to change the playbackrate
- for example, the user agent may be playing a live stream; the user agent may
be unable to play media backwards (due to limitation of the media format - no
keyframes) / at a high rate (limitation in hardware) - and 'faking' a playback
rate with seeking behavior is not a viable alternative.

The author should be able to determine that the user agent is not doing the
'true' requested playback rate.
