What about SMIL support ?

[Minabsapi]

Searching for a way to animate SVGs I stumbled upon a specification called SMIL.
Though quite old, this seemed very promising and its early implementations were reported to be very performant. I speak in the past stance like it's a distant technology, but I was able to see it in action for the first time in an article talking about its deprecation and removal from Chrome's engine while viewing it from Firefox.

I didn't read extensively about it, but from the little I saw I still think this might deserve a second chance -- not everyone wants to tinker with CSS and JavaScript to do SVG-based animations, especially for projects not intended for the web. Do you also think an implementation in this project would be worth?
