If anything, it might unbreak things.

I have my browser set to request, in order, English, a different English, then a non-English language. Some sites (Android docs, Gitlab, F-Droid) will send me the non-English content; Google even preferentially does their AI translation thing instead of the original English.

Then for some web sites it won't matter and display the dominant language of the country that you're accessing from. My Firefox sends US English as the only preferred language, but a ton of US tech companies default to showing web sites in Japanese without a way to change it because I access them from Japan. It's pretty typical of American companies that don't understand localization and accessibility.

Most infuriating is when they do it based on GeoIP. So what I'm in Istanbul currently, I know maybe a dozen words in Turkish. But no, and also they insist on having broken language switchers.
