As Benn himself points out, Hamas has been exhausted by Israel's embargoes, fuel cut-offs and helicopter missiles. If they stop shooting rockets, there is no "indirect legitimacy" to be inferred, all it means is that they are not completely stupid, just 95% stupid. Its like saying that the total cessation of suicide bombings directly resulting from Israel's security fence and raids confers "legitimacy" on terrorist groups that discontinued this warfare after it became physically impossible. The core ideology of Hamas precludes it from ever becoming "legitimate". Jomo Kenyatta's MauMau group wanted the Brits out of Nairobi; they didn't also seek to throw the Brits out of London, Manchester and Liverpool.
