Excellent points.

SMIL usage is high so it's just being deprecated in blink to get the word out, but not removed just yet. If you're planning to ship both web animations and SMIL, I hope we can get everything you need in web animations before SMIL is finally removed. If you have specific examples you can share, please do post on the smil blink-dev thread.

SMIL support is rough in the old android browser. I suspect using the web animations polyfill will be a safer path than trying to support the SMIL edge cases.

Can you elaborate on it being deprecated in blink just to get the word out? Will that not ship out to Chrome users?

Yeah, it will ship to Chrome users. The effect will be a console warning that SMIL will be removed. You should start seeing this in Canary in the next 1-2 days.
