In order to understand how best to kill IE11, we need to look back to how 2 previous versions of IE met their fate: IE6 and IE8. By examining the strategies employed to kill browsers, we can look at current efforts to sunset IE11. We can predict and evangelize for what may ultimately do it in, finally freeing the JS community from the burden of ES5.
Interesting historical analysis but I think that attempting to “kill” browsers is a misguided goal. I think the right way to move forward here is Oliver Williams’ idea of applying the “mustard cut” technique to all versions of Internet Explorer and serving those users just barebones (but useful) HTML and CSS.
