Stream types are for volume control

Deprecate methods where stream types are not used for
  volume control operations.
Add a warning in the logs about the use of stream
  types to encourage migration to audio attributes.
Since STREAM_ACCESSIBILITY is added in O for the
  volume of a11y audio, throw an exception when
  trying to use it for playback.
