It's the end of the DirectX filters in MSIE/Trident, sure - but that's a public stance that was announced along with IE9 a couple of years ago. (I'm not an IE developer but I work closely with them - my personal understanding is we ditched DirectX filters because they don't mesh with the rendering changes made to Trident and because CSS3's features do all of this anyway).

As for WebGL, I'm not aware of any changes to our public stance that it's a security liability what with allowing untrusted shader programs to run on hardware directly, let's wait and see - maybe they've decided they will allow it but only allow GL primitive calls without shaders, or only allow predefined shaders?
