This is a great example for the “Chrome is the new IE” debate: that’s a feature which would immediately make the web better but they held back support for a standard, hardware-accelerated format trying to force mainstream adoption of their own format which had limited tool support and never performed enough better than JPEG/PNG to be worth the trouble for most sites.

You think it's good that people keep using gigantic GIF files rather than smaller videos? There's no technical reason to prefer the GIF format — it burns data transfer, requires more CPU, and has terrible quality.

I prefer <img> elements never to animate at all, regardless of format. Animations should use <video>.
