MDN doesn't like it

There are a million metrics that can be used for fingerprinting, the notion of avoiding language detection because fingerprinting seems a bit weak - it’s pretty hard to fingerprint me if I’m not willing to fumble your site to configure my language, and I assume for non English speakers hard locking browser resolution to 1920x1080 to prevent resolution fingerprinting would presumably be a more usable limitation.

Edit: and ‘a user might not be the owner of the computer and therefore the accept language might be wrong‘ sounds like a UI problem that a ‘file -> set language’ workflow would solve.

Agreed

Accept-Language is far more under my control while traveling than my IP address. Especially for services that actively block VPNs.
