An option to prevent emails from being shown to administrators#824

I would like to see an option to disable the feature that allows you to view the emails of all members of your board as an owner/administrator/moderator. I thought that custom SSO did this already, but it seems that the email is only hidden when I give the account administrator or moderator. I’m not going to be giving everyone moderation permissions, but I want to respect the privacy of the people that are joining the board, while still allowing for email notifications. From my understanding, this is currently not possible.
