WHY IT NEEDS A POLICY

Why remove_email_label needs a policy

Removing a label from an email modifies the email's metadata (label/categorization) but does not delete the email itself. This is a reversible modification—the label can be re-applied—making it a Write operation. Misuse could disorganize email organization but has limited blast radius.
