If you ask about vanguards, I can tell these do work in Whonix when conflux feature is disabled (I do not have a Github account at the moment to post about it there). While built-in vanguards-lite provide a decent protection for client connections of most Tor users, “vanguards-full” are still useful protection from more sophisticated, long-term Guard Discovery attacks against Onion Services. For mikeperry-tor/vanguards to work, user can simply add “ConfluxEnabled 0” to torrc. Vanguards errors began when conflux was introduced, both Mike Perry and Tor Project still ignore this issue. It might be worth to note on Whonix wiki for advanced users.
