I agree with Jordan’s comments. From a technical standpoint if the plan isn’t a “box” the loads don’t easily resolve themselves and additional members (beams, braces, purlins, columns, struts, ceiling beams, tension rings, etc) will be needed to support the real world conditions.
Section 3.5 - Roof Systems of the Wood Framed Construction Manual provides the most usable language I’ve seen, although it is still lacking.

Subject: Conventional Wood Framing
In conventional wood framing, are vertical members required to support hips, valleys and ridges?
Are there any better references which are more definitive than the single paragraph I’ve found in the UBC?
TIA,
