I agree that Wine (well, anything) should meet the user's expectations without the user having to even be aware of their expectations.  Unfortunately, "respecting" LANG does not lead to this...

First, the language and formats have nothing to do with the keyboard layout (the U.S. flag in the input menu).

But, more importantly for this discussion, the fact that LANG will be appropriate for you and probably Gert does not mean it will be appropriate "often enough" for Wine to rely on.  As I have said, there are many ways in which users configure their language and formats settings that will not be properly reflected in LANG (and, indeed, cannot be).

You are suggesting using a proxy for the real thing rather than the real thing.  If we want to maintain the "magic", Wine should just use the settings from System Preferences directly (via CFLocale, CFNumberFormatter, and CFDateFormatter), with an optional way to override them for those rare users who want Wine's behavior to deviate from the system's.

LANG doesn't help maintain the magic.  It's a hindrance.
