The COORD is busy doing things the COORD has always done. And most of the time is also the Supervisor. Every tower has a COORD position but Sydney is the only one now to speak on air due to Metron. SMC is way to busy to check compliance so the COORD does it.
The way things stand, the COORD position cannot act as ramp as they are too busy with their regular duties.
Staff it from 0600 to 2300 and they could.
