I'm working on that right now, actually. Though it will be a while before it's ready to see the light of day. There are a couple of challenges. The first obvious challenge is consistent rendering and performance. The sheer number of targets is overwhelming - browser/ios/android/tv/etc. The second less obvious challenge is to clearly distinguish what designers are responsible for, vs what developers are responsible for. Some things are easy - "what should the text color be", for example. Other things, like determining accessibility roles, are less obvious. There needs to be a tool that allows designers and developers to collaborate while maintaining control over their own domain. Not an easy thing to pull off.
