group role is fine. So, if we put a role of group on video that would be
fine for roledesc.
SVG <g> has native host native semantics of "group" so, we don't need a
role as the computed role would be "group" so we could put it there.
Keynote/Powerpoint: Section has a default native host language role of
"region" so its computed role would be "region" and therefore the spec.
text would allow for a roledesc on that.
Looks like those would all be fine.

What about the rest of the examples I mentioned?
1. <video> in HTML might default to <video role="group"
aria-roledescription="video">
2. EPUB chapters might default to role="section"
aria-roledescription="chapter"
3. SVG could use <g role="group" aria-roledescription="chart">
4. Slides in web versions of Keynote/PowerPoint could use <section
aria-roledescription="slide">
