They are good only in close proximity, they are very strong and (hopefully)
they do not puncture.  

How about this: could the arms have been used in nest building, egg moving,
manipulation or perhaps to move branches as it stalked?  I agree they were
used to assist the jaws in shredding meat.  But what of these other possible
uses.  It seems the arms could have come in handy in manipulating things the
jaws were too clumsy to handle.
