Dave Rupert:

But in the past we had browser disparity as a mechanism for delaying bad ideas from becoming ubiquitous so they could be hashed out in a Web Standards body. Some of the best ideas we have today, like CSS Grid, were pioneered in one browser (IE10) and then polished in a Working Group. If V1 of -ms-grid was now the de facto standard, we’d have some regrets.
