Well, when Mozilla and others argued that "IE9 is not a modern browser", a lot of other people laughed at them because they thought IE9 doesn't need to support "many HTML5 specs", just a "a few good ones". Now you see the consequence of that. The reality is that IE9 is still about 2 years behind in HTML5 specs adoption, and you can easily tell that from the HTML5test.com site.
Also, IE9 is still a pretty niche browser version. If they were to find an alternative for IE9, then they might as well find one for IE8, which has a much larger market share.
