Everytime there's a proprietary "standard" (zip->gzip, gif->png, ...) the gnu people clone it and release something of equivalent functionality. I suspect that this will continue to be true - no "standard" which requires licensing is going to be adopted. The end effect will be be to render the W3C (even more) irrelevant.

It may not matter. Its not like we've seen anything good come out of there in awhile.
