>HTML5 video wasn't uniformly supported across browsers
It's still the case, IMHO. For example, mobile devices are a lost battle, in my experience, when it comes to HTML5 video (with autoplay and without controls). So MC ends up serving the straight up GIF to them.
I hope animated WebP becomes a thing but I have my doubts. I'm not sure whether the three major browsers will support it to an extent that it's actually sensible to use animated webp.
