Just because the current MOD can't envisage a future need for a use of some particular form of warfare is not a good reason to discount it.
Pre the Falklands campaign, the Nimrod entered service without air-to-air refuelling 'because it could fly the sortie lengths contemplated without A2A', and without a bombing system 'We are MR, old boy'. Availability of a long range aircraft already fitted with Inertial Nav, and with refuelling capability and bombing software would have enabled the Black Buck missions far easier and more effective. Staff College concentrates on how to fight the last war (or the war before the last) more effectively - not to think ahead.
