I'd love to see a "Can-I-use" browser extension when looking at articles like this.

Occasionally a project requires IE 10/11 support (state government work) and it's such a shame to get excited about an impossible CSS approach.

I'd love to see a "Can-I-use" browser extension when looking at articles like this.

I agree, though what I would find really helpful is not just can-i-use but should-i-use, taking into account not only feature availability but also quality of implementation. Even if a feature is theoretically supported in all major browsers, it’s not much use for a production site or app if what you actually see on screen in at least one of those browsers looks terrible, for example because of bad anti-aliasing or colour handling or animation calculations. I’ve been building new UI/design systems from scratch for a couple of projects recently, and it’s amazing how often that still happens, even with popular CSS features used to implement relatively simple effects.

caniuse.com reports whether something is too buggy to the point of being unusable in a different color, and has footnotes for whether something has some quirks/caveats but is otherwise usable

That’s true up to a point, but caniuse and I sometimes have different interpretations of what is too buggy to be usable. Rasterising vector formats and working with colour seem to be two common triggers for poor rendering, with extra chances for visible glitches if they are used in combination and a bonus if animation is involved as well.

IE 10 has no TLS 1.2 support. I think you can now safely drop it.

What's everyone's opinion on simply forcing users of IE11 to upgrade / use a different browser?

I understand that one should aim for a certain level of backward compatibility, but when does the time come to drop IE11 support for good?

Especially as a smaller webdev-shop, how would one even come up with the resources to maintain that level of compatibility? Eventually there is a trade-off where one may end up losing a (hopefully reasonably small) percentage of customers in exchange for focusing on the experience of those customers who are more up to date, but it's a tricky decision to make.

IMHO totally depends on what you are doing and who your users are. Generally going for graceful degradation should keep a lot of stuff usable for outdated browsers, even if not full fidelity/pretty, and that often should be enough. If you have lots of IE11 users for whatever reason (i.e. I believe in some countries rates are a lot higher) it might be worth the effort to make it better for them. If you ship an internal app for a company that rolls out a newer standard browser everywhere, target that.

Basically none of this supports IE 10/11 (flexbox one works, calc works, and that's probably about it). Chances are if you see a cool new trick, it doesn't support IE 11.

Seems that Microsoft is sunsetting IE11 [1], I wonder if that would nudge the world towards less IE.
