No extension in hardware can be supported in webgl without webgl standardising the interface to the extension.

eg. making a website that is not compatible across multiple platforms.

As in (1) the extension interface has to be spec'd, as the binding to any given extension has to be standardised in webgl.  If GL can't support it, the chances are that WebGL can't either.
