`BELONGS_TO` means a user owns an email address. `PRIMARY_EMAIL` means a user authenticates with that email. So right now, you get a proper error message if you try to change your email back to your old email address (because you own it already). I will make sure to delete the old email so this will be no problem anymore. But maybe in the future we might have multiple email addresses per user and then it makes a big difference to use `PRIMARY_EMAIL` or `BELONGS_TO`.
