If you do not include it then then you are not updating address list
of the other end. See my previous email to the list, i.e. would adding
follogin text help: 
----------------------------------------------------------------------
    The NO_ADDITIONAL_ADDRESSES notify is needed, as otherwise it
    would not be possible to distinguish empty DPD message from
    address update message that does not have any additional
    addresses. Now we can distinguish them, as DPD is empty
    INFORMATIONAL exchange and address update with no extra addresses
    is INFORMATIONAL exchange having only N(NO_ADDITIONAL_ADDRESSES).
    Both of them can have other additional payloads like N(COOKIE2)
    etc.
