YouTube intends to use MSE to improve accessibility by offering the user
the ability to switch content streams on the fly. Currently we do *not*
plan to implement this using AudioTracks/VideoTracks but rather by
switching the streams that get appended using JS. We are doing this so that
the feature can work reliably across all devices, including those which
lack the technical capability to support A/VTracks.

This supports Aaron's objection; conflating the user-facing goal of
improving accessibility by having the ability to select more appropriate
content and one technical implementation of that goal will limit the
adoption of other strategies which have broader support.

Thanks,
Steve
