Using Internet Explorer support info from browser-compat-data

[Semigradsky]

browser-compat-data from v5.2.0 no more adding new data about IE/Edge legacy support info - https://github.com/mdn/browser-compat-data/blob/main/RELEASE_NOTES.md#v520
And in the future existing data will be removed.

caniuse.com currently is showing data from browser-compat-data. And for some new properties it can show incorrect data

For example - https://caniuse.com/mdn-css_properties_hyphenate-limit-chars
IE 10+ has support via prefix but this info wasn't added to browser-compat-data - mdn/browser-compat-data#18369

Possible solutions:

• mark IE/Edge legacy support info from browser-compat-data as UNKNOWN
• add info about such features to this repo
• ... smth else?

In a week, Internet Explorer is going to be permanently disabled by an Edge Update on Windows 10 (it was never present on Windows 11).

Globally, IE use is about 0.57% for 11 and 0.16% for 6-10 (source: CanIUse). Legacy Edge has it even worse, at 0.02%. Realistically, these numbers will only ever go down.

Opera Mini has 0.97% global use at time of writing - how many people do you see testing their sites in Opera Mini?

Thanks @Semigradsky for sharing this. For now I've added a warning icon with tooltip informing users of the state of IE support from MDN BCD (will only appear on the MDN BCD tables). Once it is completely removed it will appear as "unknown". Will probably remove the browser from caniuse soon after that too.

Will probably remove the browser from caniuse soon after that too.

While I hate IE from the bottom of my heart, I'd like to mention that for sure some poor souls out there will have to support it till the end of time in web terms, i.e. via

Microsoft has announced support for IE Mode through at least 2029, with a one year advance notice prior to retiring this variant of IE11.[6]

To make it less bad for those souls, I'd ask for a good reason to remove the support data, i.e. perf for all others or something, and not remove it just because.

@Sora2455 UC & Opera Mini are your only way to go if all you have is a dumb feature phone, if you only have usable 2G GPRS/EDGE coverage throughout the day or you monthly data usage quota is too expensive.

Not sure how much of that is Mini & extreme, though, and the proxy may also fake the User-Agent at times
