Why?
The groundcrew are entitled to and received EXACTLY the same gongs as any other serviceman serving within the UK in a frontline capacity. Why should they receive any more than (say) Fighter Command, Coastal Command or Army Co-operation Command groundcrew?
And indeed, why should there be any need for a separate medal for Bomber Command aircrew, who received the same medals as other UK-based frontline aircrew - whether that was 'Air Crew Europe', 'France and Germany' or whatever.
The idea of a separate Bomber Command campaign medal is divisive nonsense, in my view.
