Yup.  And every time IANA hands another /8 to some RIR, MAPS has to unblock
it.  Has that happened with 98.0.0.0/8?  Doesn't appear so:

  IANA (RESERVED-8)

   Netname: RESERVED-8
   Netblock: 96.0.0.0 - 126.255.255.255

      Internet Assigned Numbers Authority  (IANA-ARIN)  [email protected]

I've thought sometimes that a BGP feed that only included iana-reserved
and rfc1918 space, not spammers or other policy violators, would be a
popular thing.

I've also thought that if routers could filter based on lookup up source
addresses in a BGP-made RIB, rather than just destination addresses, that
the whole filtering-by-remote-control industry would appreciate the hell
out of it.  I'm pretty sure that both the 12016 and M160 have the hardware
it would take to do this at wire speed, but I'm also pretty sure that the
market for this feature is perceived by both vendors as "small."
