We are a little unique in terms of essentially having a “free” rank in the Canadian Cpl. In Latvia it was difficult to explain but everyone just goes by their OR code anyways.No need for a position like that, the WO/PO1 rank cover that responsibility.
Take at look at the NATO equivalencies charts for ORs, if you're not familiar with them it might help to clarify what Canada does compared to the UK, USA, and others.
A thought on the “benefit” of a punishment being more severe because you skip MCpl if demoted. If the chief advantage of something is you punitive power because of it, I’d argue it holds no value at all.
