Metering is not a critical/safety component of the grid. It's an important business component, but it does not by itself guarantee safety or preclude safety measures from kicking in.

There are other systems that are used to monitor load/draw on the grid and ensure safe operation.

Things like smart meters can be connected to the public net and if compromised just cause a headache.

Your critical safety system should not be connected to public networks or at least should have strong protections.
