Actually it is. From RFC 1700 ("Assigned Numbers")

      (a)   {0, 0}

         This host on this network.  Can only be used as a source
         address (see note later).

which RFC 3330 ("Special-Use IPv4 Addresess" expands as

   0.0.0.0/8 - Addresses in this block refer to source hosts on "this"
   network.  Address 0.0.0.0/32 may be used as a source address for this
   host on this network; other addresses within 0.0.0.0/8 may be used to
   refer to specified hosts on this network [RFC1700, page 4].
