Interesting! I never considered the case you and the other replier brought up where people might want to browse different sites in different languages. Learned something new today, thank you!
I suppose browsers could/should add support for this use case, none of the major ones do as far as I know.
At the very least, I maintain that sites should use Accept-Language: as a default, absent any site-specific configuration that they offer. One of the huge things I hate about Google and a few other sites is that they deliberately ignore my Accept-Language: header and instead rely on IP-Geolocation. So if I'm traveling in another country, suddenly Google and those other sites change to a different language on me. Maddening.
