Paul, I think there is a fundamental misunderstanding here.

The feature that this change proposal is suggesting does not depend on
WebVTT. It is simply and extension to the TextTrack API so it is possible
to fulfill FCC requirements for online video captions in the browser.
WebVTT will build on top of it and I would recommend TTML to also build on
top of it. But it does not depend on WebVTT having the same feature
implemented. In fact, it is the other way around where the TextTrack API
provides functionality that both WebVTT and TTML can build on.

So, nothing precludes the HTML spec progressing independently from the
WebVTT specification here.
