That's actually one of the use cases being considered but I don't
consider it an important one myself.

The CSS inside the caption shouldn't address the entire page but only
the video portion, so the positioning is different.

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.

except that we're expecting HTML rendering engines to display the
content and they would rather receive HTML content with timing
information. Converting TTML into HTML isn't an issue even if it has its
limitation (not all style properties from TTML can be done in CSS yet).
I guess the issue is who is going to do it, the video providers or the
web navigators.
