I hope this makes its way into web browser rendering. I've been working on a "game engine" using SVG in the browser. When I started, everything I read said don't - because performance. However, manipulating an SVG using a reactive framework (I use Vue) makes for very readable code. Our game client is meant to be a "reference" client so readability is more important than performance, which just needs to be "good enough." However, a significant boost in SVG rendering performance would be amazing.

edit: although, as I look more deeply, I may be misunderstanding and this may not be something that would benefit existing SVG browser rendering in any way...
