In the works! You should be able to use the existing <youtube-video-element> [1] with the HTML side of v10 today, but we're working on porting over the other media elements into the new architecture for better React support.
It will be interesting to see how you handle acces to youtube player settings and cc. This is where other player wrappers fall down.
Plyr did a good job of removing the branding via some clever css, but its annoying you cannot access settings and cc. One idea for a cc button is to always have cc on and then toggle the height styling to show/hide it
