Consider

publisher1 = Publisher(RootDirectory())
publisher2 = Publisher(RootDirectory(), session_manager=SessionManager())

Are there significant differences (i.e. in performance) if I use
publisher2 instead of publisher1 in the case I do not login (i.e. the
user is None)?

I am wondering if I could just user publisher2 as default publisher even in
applications that do not need session management.
