Of all the specifications, words, and complexity this article mentions there are only 3 really costly areas that the web browsers devoted a good portion of their net worth to solve: * Presentation (generally and CSS specifically) * JavaScript JIT (and other performance pipelines, DOM efficiency, caching architecture, and so forth) * and accessibility I know there is much more to the web than that and notice that I did not mention security. Those 3 things took years and lots of research and failure to get to today's status quo. Everything else is comparatively trivial when compared on the basis of man hours and money spent. If you can really nail those three quickly and cheaply then everything else is trivial from a perspective of money and time.
