Call me a cycnic, but I don't suppose there will be a UNICOM frequency until there is an accident attributable to de-confliction and aircraft not talking on the same frequency.
The whole aspect of the withdrawl of the frequency left a lot to be desired. NATS did not officially notify either the CAA or the Home Office hence the reason that it was still in the PAOM. Word of mouth to the HO Police Aviation Adviser.
I've found that the relevant ATC agencies are very helpful when in or close to CAS. It is very difficult to find a frequency these days to speak on. I still find it hard to believe that a facility, purely for flight safety, is withdrawn and other organisations and airlines still have official company frequencies.
