Pretty neat!

Works for me. That said, I would not be surprised if we end up needing a way to talk about the "list of timing text tracks" that are associated with a given timing object in the end (the "time marches on" procedure uses the list of text tracks for instance), which would require re-introducing that list one way or the other. That's not needed right now, though.

I agree with pursing the two approaches in the group but the spec is already the second bullet there, so I don't think it makes sense to present the approach within the spec. I updated the prose accordingly, linking to the JavaScript sequencer implementation in a note.

What strikes me as good is that it presents a possible solution based on concepts that people fluent in media matters should already be familiar with. Given enough support for the feature, this can be entirely discarded in favor of a "cleaner" solution as described in the issues!
