Short explanation why the 'mail-to-root' is exempt from priv checks: To ensure backwards compatibility, the 'mail-to-root' target does not require the `Mapping.Use` privs. This is needed due to the fact that this target is used as a fallback in case no other target is configured for an event. For instance, the /node//apt/update API call only requires Sys.Modify for the node, but it can also send a notification. If we were to require Mapping.Use, we could break the apt/update API compat in the case that a notification shall be sent, but without any configured notification target (which will then default to 'mail-to-root').
