@maxbob why? This is not a new standard. This is a new engine for implementing web standards. This is essential to the health of the Web. If anything, the diversity of browser engines helps the interoperability. It seems counter-intuitive. Right now, there are Blink, Gecko and WebKit only. Presto is dead. Trident is dead. EdgeHTML is dead. Without multiple engines, there is no need for interoperability and the winner takes it all. And it's where things start to go wrong.
