[dukoid]

I'd argue that this is only a secondary purpose at most -- and in this case not intended at all. Also, there are other uses of the word forking outside of VC. For instance, I have heard it in the context of threads first... O:)

It doesn't have to be intended. It's just that every time you write or speak you communicate group membership. For example, there are further implications about group membership when you correct my interpretation of forking. Another example: unless it's a typo, your grammar ("I have heard") indicates that English is not your first language.
