So animated GIFs can be replaced by Animated PNGs with alpha blending with transparent backgrounds and lossless compression! Some nostalgia from 2000s websites can be revived and relived :)

Curious if Animated SVGs are also a thing. I remember seeing some Javascript based SVG animations (it was a animated chatbot avatar) - but not sure if there is any standard framework.

Yes. Relevant animation elements:

• <set>

• <animate>

• <animateTransform>

• <animateMotion>

Slightly related, I recently hit on this SVG animation bug in Chrome (that someone else found):
