As said multiple times before, the other programs *do not use* 
setlocale() to switch languages nor list languages, but rely on 
environment variables. That is why they do not need to do anything, and 
thus have not faced this problem.

Note that KDE does provide the user a list of languages, but it does not 
use gettext, but instead uses its own glibc-derived implementation for 
translation, with file format being the same.

I think the reverse would be more useful here, i.e. not smart enough to 
try "de_DE" when "de" is called for.

Yes.

I'm not aware of such a way.
