Under existing policies, there is no way for IANA to carve out pieces of address blocks. The /8s with pieces carved out of them by the IETF are/will be allocated to RIRs with an understanding that the RIRs aren't supposed to allocate the IETF-designated reserved chunks (which, presumably, they won't).
