I believe that you are confusing RAFCARS and 'Managed Path' with the previous 'Link Up' scheme. Now discontinued?
The MCAWG approved the current accreditation scheme for military pilots towards JAR-FCL requirements; this has made it simpler and cheaper for military pilots who've achieved the qualifying criteria to apply for either a CPL/IR or an ATPL.
Precisely what equivalent scheme could there possibly be for 'other aircrew trades' except Air Engineers under JAR-FCL 4? The JAA does not recognise navigators, AEOs or even ALMs in licensing terms - so what is your point?
