Does this mean that you consider it more of a want than a need?  Do
you consider some sort of mechanism (other than a div) which supplies
a text alternative for a video key frame  is not a functional
requirement for HTML5?

This is a core disagreement. "Access for people with disabilities is
essential. This does not mean that features should be omitted if not
all users can fully make use of them but rather that
alternative/equivalent mechanisms must be provided. Example: The image
in the img element is not perceivable by blind users. That is not a
reason to drop the element from the specification, but is a reason to
require mechanisms for adding text alternatives." [1]
