The concerns around inefficiencies are on two levels. There are risks that an additional and unnecessary layer could be introduced that does not necessarily add a huge amount, though it could be argued that it is an addition in democratic accountability and strategic oversight.

Both of those scenarios could potentially cause problems and they are the kind of things that need to be looked out for.
