Official support for animations, yes! This feels so nostalgic to me, I have written an L-system generator with support for exporting animated PNGs 11 years ago! They were working only in Firefox, and Chrome used to have an extension for them. Too bad I had to take the website down.
Back then, there were no libraries in C# for it, but it's actually quite easy to make APNG from PNGs directly by writing chunks with correct headers, no encoders needed (assuming PNGs are already encoded as input).
