I agree Roderick, but thanks to the unbendable and intransigent nature of N4 CfE dogma, and of those in charge of guarding it, this will not happen, because at N4 a 100% pass of all outcomes is required (CfE is of course just rebranded Outcome Based Education of the type discredited in every other territory it has been tried, the rebranding exercise being done to avoid people Googling OBE and discovering the truth). The fact that once you reach and go beyond N5 summative assessment and sampling of knowledge and skills becomes the norm for overall course awards matters not a jot to them.
