So anyone who supports svg 1.1 supports this automatically. I guess it helpa define/narrow a small svg subset to target if you write a new renderer. For instance rendering with JavaFX primitives, this would maybe be achievable
And this new thing also sounds kinda like a subset of svg..
It's pretty bad marketing to call a different product by the same name. Particularly when it chooses a totally different side of the trade-off versus its homonym. Not only have I never heard of SVG Native, I'm confident that I'm going to forget what it is in a few days because I don't have a proper name to remember it by. Also, the adjective "native" here gives me no useful information as to what problem it tries to solve — how do I infer "simplified" from "native"?
Maybe there isn't any need for a simpler vector graphics format because no one is using TinyVG, either.
