If timed text were being integrated into HTML, then I think you'd have a point. In which case I'd argue that HTML+TIME is probably the most sensible starting point.

However the model seems to be having it be associated externally, like a video, audio or image format. Which, since the captions and HTML are likely authored by different people, and come from different servers, seems like the most sensible model, in such a case how the timed text is structured seems somewhat irrelevant to me.

As I said, due to its lack of use of HTML and CSS. SVG and Math introduced new elements that simply weren't in HTML. TTML uses paragraphs, which already exist in HTML. In addition, both SVG and Math are using CSS, so it makes their integration with HTML easier.

If anyone has any sample videos or still from videos showing real-world use of timed tracks in ways that demonstrate possible features I haven't considered, please let me know. So far, I and some others in the WHATWG list and on #whatwg have collected the following:
