So, because it is more recent, it should not be taken as seriously as others?
Doctrine is the starting point. If you want to deviate from doctrine, it is fine but you better have good reasons. You don’t deviate from doctrine because the doctrine said we could... In this context, I don’t see the RCAF accepting giving the residual authorities away anytime soon.
FWIW, Sense, Act, Sustain, Shield, Command is joint doctrine (which yes, was based on Army doctrine) but these functions apply equally to all services, including SOF, although some, like you mention, added their own functions.
