CNC split over Canterbury appointment?

The Sunday Telegraph has this report about a split in the Crown Nominations Commission entrusted with the choice of the next Archbishop of Canterbury. It would certainly be in line with the impression given of an increasingly jittery, unstable and unselfconfident institution.
However, isn't everyone hugely overemphasising any authority or even influence the Archbishop of Canterbury actually has over his own church? In recent years we have seen the General Synod and the dioceses repeatedly ride roughshod over the clearly expressed wishes of the present Archbishop both in relation to adequate provision for the C of E's traditionalist minority and over the fiasco of the Anglican Covenant. 
It will take more than just a name change at the top to heal the Church's apparent death-wish and prevent a headlong rush into historical oblivion.
