On general principles, I'm rather reluctant to trust *firmware
providers* of all people to be a reliable source of...well...anything at
all. Is this really a good idea? Doesn't Murphy's Law Of Firmware
Engineers pretty much predict that someone is going to set the 'firmware
language' variable to Chinese even when the firmware's actually in
English, or something? This is the kind of thing we want to have very
few 'false positive' results on, given that if we get it wrong, there is
a very high chance the first screen of the installer will inexplicably
look like gibberish. I think people are usually willing to tolerate it
defaulting to English when they speak something else - English is pretty
much the unofficial lingua franca of Tech In General, if nothing else,
everyone's pretty much resigned to it by now - but people (of whatever
nationality) are far more likely to find it problematic if it defaults
to a non-English language which is incorrect. It may even be politically
sensitive in some cases (hiya, Greater East Asian Co-Prosperity Sphere!)

Frankly I'm not 100% convinced that it's a good idea to try and guess
language even from a fairly reliable geolocation mechanism like ours.
It's still not 100% reliable - people behind corporate VPNs can be
routed through just about anywhere - and even when it gives a correct
geographic location, what the hell do you do for, say, India? Where
you'd need to have house-level accuracy to have a snowball's chance in
hell of guessing what language someone speaks? I mean, even the US's hat
is officially a bilingual country, and the US itself is pretty much
unofficially bilingual at this point (please don't take this as a
political statement, sensitive USians, it's a purely pragmatic one: we
can't 100% safely assume someone wants to install Fedora in English just
because they are geographically located in the United States).

I know vpodzime is thinking of changing the whole language/location
logic for F20, which is probably a good thing. If we have a question
which is simply 'what country are you in?' - as distinct from 'what
language do you speak?' - it would seem reasonable (though still
somewhat politically fraught, in a few cases...) to guess that from
geolocation, and populate the 'most likely' list of languages from
langtable's association of languages with countries. But just going
straight to guessing a language, cold, based on location, seems to me a
mechanism that's prone to failing in embarrassing ways. Apologies I
didn't bring this up sooner - we may have to eat it for F19, but I'm
just _really_ not sure it's a great idea.
