I have not followed this from its beginning. But the definition for C&C contained in the ASCE 7-05 Commentary may shed a little light. Roof trusses are specifically cited as an example.
If the code says so, then have to comply: unless consider unconservative and willing to argue. But codes do change, and often need to. The commentary also basically supports what Christopher Banbury recommended.
And that principally is: both MWFRS and C&C pressures may need to be considered for the one element, within the appropriate context.
