Comment (by joedolson):

 We should conduct some up to date comparison testing between the
 accessibility of the native elements and MediaElement.js; last
 documentation I saw on [https://scottvinkle.me/blogs/work/how-accessible-
 is-the-html-video-player native video accessibility] was not favorable to
 the native video player, but that was five years ago, so it's probably not
 totally accurate anymore.

 Updating shortcodes to use native HTML elements will probably visually
 change a lot of sites, since the HTML wrappers for mediaelement.js are
 common targets for style hooks. I'm not sure that's an easy path to take.
 Just a casual search on the `.mejs-container` wrapper
 [https://wpdirectory.net/search/01HZMK3HKWBNTTVKQRHNAAF70P shows
 significant use in themes].
