Not sure who you've been talking to. I can tell you in my neck of the woods instrument procedures are not scoffed, considering we shoot the ILS or PAR to mins in a snowstorm every week in the winter.
The point of saying that everything they learned in UPT is motherhood and will be covered in the first 5-10 minutes of the brief is not to say that those things aren't important. Any 11F who's been around more than a year or two knows enough dead pilots to disabuse themselves of that notion. The point of that statement is to say that you are expected to maintain proficiency in those areas yourself so that when we're in an LFE adversary coord, followed by blue mass brief, followed by package coord, followed by 20 minutes of flight fill-ins, we don't spend what little time we have left briefing up the approaches.
Last I checked it's not "11Fs" trying to trim the fat at UPT, but some enterprising General Officers. Those of us who actually instruct at the FTU or MQT in the CAF would tell you that those decisions are making our job harder and more dangerous.
