my guess is the same.  still, and for the record, rfc 2317 speaks thusly:

| 5. Operational considerations
|    This technique is intended to be used for delegating address spaces
|    covering fewer than 256 addresses.  For delegations covering larger
|    blocks of addresses the traditional methods (multiple delegations)
|    can be used instead.

hopefully the implementors of such provisioning systems will read this.
