Do you need the gender of the current user, or of another user?

If you need the gender of the current user, all you need to do is
depend on mediawiki.user and mediawiki.jqueryMsg, then just pass
mw.user (the user object) as the parameter to {{GENDER:$1|...}}. If
you need the gender of a different user, I'm not sure that's even
available.

I need the gender of a different user (the one who uploaded a given image - not even necessarily a user on the same wiki). It is available via the users API, [1] what I need to know is whether it is necessary.
