I guess the comment that Dave makes is that the UA should have the possibility
to decide what tracks to expose to a user through a track menu that is
automatically displayed as part of the video controls.

I am further assuming that the idea is that if a user has set their preferences
to be to not see any video tracks (e.g. because they are blind or have their
eyes elsewhere) and therefore prefer to always activate the first appropriate
audio descriptions track (being appropriate because it's in their preferred
language) then the UA should not display these unwanted tracks in the track
selection menu.

I am further assuming that the idea is that this would remove complexity from
the user and simplify their choices - in particular where there is little real
estate as on a mobile device.

(Dave, correct me if I am falsely assuming your line of thought.)

I actually think that this should be a user preference setting, too - or
something that the browsers implement dependent on the available real estate
and user preferences. But as a default, I agree with John that all of the
available tracks should be displayed.
