Perhaps that's not how they ought to work, but that's definitely how they work - web standards are effectively determined (e.g. in WHATWG) by a consensus (or in some cases unilateral action) of makers of browsers with nontrivial market share; and that's how this has been happening for quite some time now. If you've got 20% market share, then your opinion (and your implementation choices) matters much more than that of the multiple <1% browsers.
