I couldn’t be more in favor of ditching IE11.
As pointed out, outside of some very specific cases, such as usage in old, legacy systems, there is no reason a “normal” person would use IE.
Supporting IE makes development of pretty much any web app a pain, slowing it down considerably. Stuff that just works in any normal browser for years now, often just doesn’t in IE. I am not a developer per se, but I happen to work with some web layouts from time to time, and at one point I just changed my approach and started ignoring IE (or rather throwing an error message about lack of support), because it is simply not worth it.
Please, just ditch it.
Thank you.
