Discussion on: How to polyfill JavaScript fetch function for Internet Explorer

I still want to support IE11 as it comes pre-installed on Windows machines alongside Edge by default. It's okay to support it in this way since the polyfills don't affect performance on supported browsers.

I don't see any issue here. It's always okay to support older browsers and ensure good UX for them if it's viable and if it's not at performance cost, no matter which year it is.

Sure it's a hard sell but my point is that all that backward compatibility is holding back the platform as a whole. And Edge should have replaced IE.
