It's still here! It's now branded Animate CC[1], and (naturally) focuses on other output formats.
The product itself can export to SVG (https://helpx.adobe.com/animate/how-to/export-image-svg.html), but I get the impression that's only for individual frames.
Edit: https://blogs.adobe.com/creativecloud/export-svg-animations-... exports SVG animations, but only, it seems, for special types of documents ("From here you simply create a new “Snap.svg Animator” document type and begin creating content s you would normally. Publishing your content then generates a boilerplate HTML file along with all the assets you need, giving you an example of how to embed your animation into a webpage.")
For previous projects, I've had workflows where images were extracted from one place, added into existing SVG files and Inkscape was scripted to slice up and export sections into PNG files. I can't see a way to do anything similar with Affinity Designer.
Also what does "ml" mean?
