    Add some (ifdeffed-out) experimentation with file service providers
    
    Kept in #if 0 in case some similar experimentation needed in the
    future.
    
    It might be interesting to be able to tweak behaviour based on knowing
    on what kind of storage the doument is located, but alas, that seems
    not possible.
