    make bereq.uncacheable read-only outside backend_fetch
    
    Writing to bereq.uncacheable in backend_response and backend_error would only
    make sense in the context of a retry. In most real world cases, writing to
    be*resp*.uncacheable would be intended in backend_response and backend_error.
