Accept-language is systematically broken for minority languages within dominant language communities. In New Zealand, a country with three official languages and a textbook case of language revivalism, I've never met anyone without a degree in computer science who sets accept-language, and I've never seen a computer system which ships with all three official languages selectable. Most computer systems ship with en or en-us as the default.

If there were silver bullets in this area, the solution would be obvious and we wouldn't even be thinking about having this conversation.

As I've now said...4 times, I don't think we'd be using geolocation.
We'd be using the accept-language header. See

The large expat community in some parts of the Arab world might prefer English over Arabic. India would want to do things by state, and a whole new front would emerge in the Israeli Palestine debate.
