HTML5 is increasingly trying to restrict ARIA usage in the DOM as part 
of an effort for better HTML practices. That is a growing problem.

The <video controls> UI element is only partially implemented by many 
vendors.
It is a very basic, immature component in most code bases.

Yes, it can be "fixed" by using JavaScript and ARIA. Use an image tag 
and JavaScript to swap in the video as a sibling, and implement JS+ARIA 
based video controls. It fixes all sorts of issues. But as a long term 
solution, it's quite verbose and heavily relies on ARIA flow vocabulary. 
It doesn't work well for static pages.

It would benefit many an author if the stock <video controls> UI were 
higher quality. If authors are going to use native controls, those 
controls need to be easy, fast and have quality. Otherwise authors are 
stuck using media players through the <object> tag or developing large 
component libraries with JS.
