The server DUID is mandatory in the replies from the server, so adding
it to the Option Request option is in best case redundant.

 15.3. Advertise Message

   Clients MUST discard any received Advertise messages that meet any of
   the following conditions:

   -  the message does not include a Server Identifier option.
 ..

 17.2.2. Creation and Transmission of Advertise Messages
 ..
   The server includes its server identifier in a Server Identifier
   option and copies the Client Identifier from the Solicit message into
   the Advertise message.
