What do you mean? I think you might be missing the point. ECMAScript 3 is almost universally supported to the letter and will continue to be for the forseeable future, just like modern x86 processors are backwards compatible with the ABI from decades ago, and hence is a rock-solid foundation for projects like GWT that compile to it.
ES3 has become the universally compatible "write once, run anywhere" bytecode VM that Java promised to be.

"Javascript is the x86 of the web"
This won't be fully true until everyone is on the same page with ECMAScript5.

Actually, I'd say that having multiple different "standards" from different vendors is a pretty good description of both Javascript and x86.
