The other primary purpose of language is communicating group membership. For example, it's reasonable to guess that you belong to the "uses version control" group by your use of the word "forking" in a non-VC context above.

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:)

[hacking_again]

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.
