Your point makes sense. My distrust comes from the fact that $militaries keep separate versions for toys they export/publish vs toys they use. See: M1 Abrams export variants, cryptography export laws (limited key lengths; restrictions mostly lifted), etc.
Tor is open source and protocol is open. You can hardly make different versions of it. I can't imagine that at least. The point of Tor is that US spy can send his traffic to whitehose.gov from Moscow and his bytes will not be different from bytes of thousands of drug addicts looking for some marihuana on dark web. FBI won't be able to tell a difference. That's the whole point of Tor. It makes no sense to maintain two versions of tor networks or something like that.
