FLIF also supports animation, so it could be used to replace animated GIF too.

Presumably if you're using animated GIF you care about compatibility with exotic/older browsers, so at best you'd consider H.264/MP4 or SVG or Flash animations.

Yes, being old/compatible is about the only advantage GIF has ;)

I agree that video formats are more suitable for many animations. Unless you have an animation where lossy is not desirable (e.g. cartoons or technical animations), and you only have pixels, no vectors. In that case FLIF (or APNG/MNG for that matter) can be a good choice.
