Default Password Nag doesnt apply to newly registered users

[dd32]

The default password nag currently only applies to auto-generated accounts, and password resets.

It does not apply to newly registered users through wp-login.php.

Attached patch adds support for it.

My only question is, Should it be applied to new users? My opinion is yes, but some sites may think otherwise, in those cases, the addition of this to a plugin or theme would remove the nag all together:

remove_action('admin_notices', 'default_password_nag');

This makes sense.

(In [13490]) Set up the password nag for newly registered users. Fixes #12143
