There are tradeoffs between implement an action immediately compared to having time to review the action for security purposes.

For example, deleting an account.

Some people may want to delete the account immediately to remove any trace.

Others may want to have some notice before the account is permanently deleted to prevent any malicious account deletion requests.

Sending a notice about account deletion to recovery contacts and allowing some time to reverse or recover the account is appreciated. This will help protect against malicious account deletion and protect against mis-understandings.
