I wouldn't be so worried about security since a user can have
BR2_TARGET_GENERIC_ROOT_PASSWD in his .config

Anyway, you end up having the wifi password stored somewhere in the overlay
anyway, so I can't see a problem here.

Or you can use an empty password to store in the .config on the version
control, and have a simple sed to replace with the correct credentials just
before the developer makes a build. In any case, having those options makes
way easier to configure a wifi than guessing the correct overlay to setup.
