Considering the MCA are making a complete "Horlicks" of their own "Future Coastguard" re-organisation (don't expect them to publicly confirm this!) , I worry about the new setup for the ARCC. Especially if the MCA cannot get over their "if it doesn't happen on the South coast it's irrelevant" bias.
Proof will be in the pudding. However the RAF isn't perfect and the ARCC have made some massive cock ups in their time, not to mention the daily cock ups of forgetting to organise a HLS or call the ambulance to meet the helo.
Not everyone/everything is perfect. That's life.
