There's momentum, and that's the why. Imagine trying to get Apple, MS, Google, Mozilla, et al to agree on a JavaScript replacement that was rolled out at the same time.

Then deal with the 5-10 years or so legacy browsers hang around with significant market share.

JS was anointed long ago, and if we knew then what we knew now, maybe it wouldn't have been so? I remember DHTML and how silly it was and how it was just a toy and BOOM! Ajax.

So here we are. Every browser supports it, none could agree to change, so we deal with what we got. Better tools are better than nothing.
