Why start/finish writing code? I'm talking about people who want "native in-browser" rendering for something other than MathML. If they want their favorite approach implemented in the browser, they're welcome to make it happen. My point is that MathML native-in-browser rending is basically already here. Of course you can use Javascript libraries like MathJax or something similar to implement whatever you want. But for people who care about native rendering, that's neither here nor there.
