Given all this background, I would suggest we keep the term "extended audio
description", since it does extend the timeline and people know it and it
has been in use. We haven't actually included the "enhanced" capabilities in
the requirements for "extended audio descriptions" at this stage - there is
no talk about hyperlinks and such.

Also, I would suggest to rename "extended captions" to "enhanced captions".
I actually like this term better, because it better conveys how we are
extending it - namely with enhanced content.

Just my 2c FWIW.
