See, https://andadinosaur.com/launch-vinegar. This extension on Safari substitutes a simple HTML5 video player in YouTube to stop tracking and ads. Also it seems to improve the video quality, at least as far as I can see.

Safari extensions are not supported on Orion and will not be.
Vlad thanks. And you are right about wanting it as a native browser option!
