Remove password for Google linked account

Accounts originally created with an email and password but are then linked to a Google account retain their email + password sign in option. While having two sign in options can certainly be useful, it'd also be nice to be able to remove one's, redundant, password.

Ive had many users message support because they have lost access to their gmail account. Password auth is there as a backup, so if its enabled, it can't be removed.
