I don't buy that. lc_collate, lc_ctype and lc_numeric are certainly
related, but they're not a property of the "language of the text". For
example, imagine an employee database for an international company. When
a user wants to print out a sorted list of employees, the language of
the text in the database (name of an employee) is irrelevant. A german
user would like to see the names in different order than an
English-speaking user.
I've seen this in practice. Also, see:
http://www.unicode.org/unicode/reports/tr10/#Common_Misperceptions
for another example.

Sure. Don't do that, that's just silly. But I don't see how that's relevant.
