...assuming I understood the question properly, it could be restated as "Can
a client use DHCPDECLINE to reject an offered IP address after sending
DHCPREQUEST?"  Implied in that is what recourse is there for a client that
doesn't like some or all of a server's offer?

...only that if a client releases the lease it is likely to get the same
lease the next time it starts the cycle....  I don't think we should be
making a change to the protocol at this point lacking sufficient evidedence
of harm caused by the current behavior, but it does seem a bit of an
oversight....
