Some time ago, a nice fellow HN user @boriselec wrote a browser plugin for, in the end, my personal use (as barely anyone uses it), that redirects all video links to their /embed variant.

/embed links are meant to be embedded in other pages and do not show any UI clutter. As it happens, they also work perfectly well if (re-)directly opened!
