You are confusing the issue here - the RN will train for SAR as they have always done - this is because as all mariners will know there is a moral obligation for all on the sea to help each other in an emergency. Often the best way for an RN skipper to help when at sea is to use his helicopter.
This is not a case of pay for one or the other (Mil or MCA SAR) but completely removed from the obligtation the government has to provide SAR around the UK coast.
Not sure what you are trying to say in your final para but I have never looked down on any fellow aviators based on whether they are RAF/RN or Civ - indeed I now fly in Civ SAR with a complete mix and enjoy doing so ...
