Yes. Just one problem I discovered recently is that no other format does looping properly.

With a GIF, you can right-click and save it, and all the looping info is inside the file. The quality is crappy, but it just works.

With all “proper” video formats, looping info is metadata, stored separately.

You can’t even go for something slightly more modern, animated PNGs, because there are warring formats and very few tools that support them.
