Well, some countries do use it (including my own):
https://en.wikipedia.org/wiki/ISO_8601#Adoption_as_national_standards
https://en.wikipedia.org/wiki/Date_format_by_country

In any case, while I do think better localization would be great, that
is a larger task and orthogonal to adopting ISO 8601 in this case.  I
think that Emacs should follow international standards by default.

BTW, shouldn't the ISO 8601 default be "year-month-day"?  It is
documented to be "year/month/day".  See:
