It is fascinating the interplay between the Chrome team, and WHATWG on SMIL. It's one of those W3C standards from the W3C's "XML all the things" years that you can tell browser teams aren't entirely thrilled with. Quick searches seem to indicate that WHATWG's overall take seems to be that all SVG animation support would be better in CSS Animation and that they'd also prefer to punt SMIL.

> It's also a bit circular to "prioritize based on how common the standards are found used in the wild" when they're single-handedly responsible for preventing developers from using SVG animations "in the wild" in the first place.

It certainly is a chicken-and-egg bootstrapping problem. Though the increasing prevalence of "Works Best in Chrome"/"Works Only in Chrome" dominance may suggest that Edge is still in a position to follow the trends than attempt to lead them on ancient W3C standards like SMIL.
