I think the whole thing is in a process of evolution, and may eventually be completely changed, just as they did with the Necrons. They've already given hints of alterations to the Space Marine creation process with organ implanatation through surgical means being partially replaced by "viral machines" ala the Blood Angels Codex. Also, there is a lot of contradiction which they rarely make attempts to retcon, particularly in the older material. It can be frustrating at times.
