Agree.  I think we want to elevate this to SHOULD in this case, even if the 
original 1034 requirement was not that strong.  Clients failing to operate 
this way presents real operational problems for AFS cell administrators.  I 
would suggest a slight rewording, so that the present text cannot be read 
to imply that 1034 says "SHOULD" in the 2119 sense, when in fact it is 
somewhat more ambiguous.
