Phil Wood recommends “firm hand torque” with their special tool and anti-seize on the threads, but it’s not like torquing a crank bolt or cassette lockring. About antisieze though, I believe are talking about with use of a locking ring, about which they say "“The use of a lockring is optional but recommended for maximum security.” Thinking about it, a lock ring could be helpful, as I can then use antisieze instead of loctite blue in order to minimize torque needed to remove if it needs servicing.
