This looks exciting, I hope it goes somewhere. I am a little concerned that it doesn't support text though. Tooling could probably render text as curves, which would be more consistent across platforms, but would take more space, and the text would no longer be selectable or extractable.
This is a file format for icons, the name isn't random. Typical applications that need icons are going to support text in other ways, like actual text, rather than anti-accessible bloat inside images.
Moreover, text in SVG files makes sense as an editable authoring format, but depending on fonts is quite bad.
I guess that's fair. There is definitely room for a more general vector format that can replace SVG that is smaller, doesn't have scripting and external references, etc.
