Currently, if you want to have a post process on objects (let's say an outline), you are missing a crucial injection point "BeforeFogAndSky" because "AfterOpaque" is too early and BeforePreRefraction" is already after fog so your pp is applied over it.
Having a "BeforeFogAndSky" just before that would solve this case.
A good test case for this is the Full Screen Sample outline scene in the HDRP Package Manager
