If I recall correctly, we discussed this at the time, and the problem
with locale is that it's not thread safe. I agree that if it were, it
would be nice to be able to use it, either with 'n', or in some other
mode just for grouping.
The underlying C setlocale()/localeconv() just isn't very friendly to
this use case.
