Comment (by sabernhardt):

 As noted earlier, people still using Internet Explorer likely are not
 doing so by choice. Let's continue supporting the people for a short time.

 ==== Level of support

 1. If a task is more difficult—or even impossible—for someone to complete
 simply because of the browser's limitations, that needs correcting.
 2. If the layout simply does not show as intended, people can still report
 and/or fix those issues (perhaps at a lower priority than other bugs).
 3. For preferences, such as using a certain color scheme, a good fallback
 should suffice.

 I know the editor has periodic IE 11 testing at least once with every
 major WordPress version, and testing with each major plugin release could
 catch more problems.

 ==== Discontinuing official support

 In a Make post, announce plans that regular IE testing will stop as of a
 certain major WordPress release. We do not need to prevent access to
 certain features in IE 11; simply make it clear that things could be
 broken.

 notified a full year ahead] of dropping IE 11 support with 365 apps (not
 Windows 10 yet), though I like the round number of WordPress 6.0.

 I suggest ending support in two stages:
 1. Back end: the editor and any admin page that requires more than
 subscriber-level access
 2. Front end: including bundled themes, theme-related functions, the admin
 toolbar, login and the profile page

 If contributors still want to test their patches in IE 11 after that, they
 can continue that without the requirement.
