Being part of nest means that you can access private members of other nestmates, but how do you access a private member of a hidden class from another class if you can not refer to the hidden class symbolically? You could perhaps use reflection or MH.Lookup to obtain direct MHs. Is that an important usecase?

Yes.  Such things are often wired together reflectively.
