Is it wrong to not use default SVP components?
Generally no. Advanced user can use SVP core and any versions of components.
manually install latest: MPC-HC (already with LAV), FFDShow, madVR, ReClock, & AviSynth
Latest avisynth has not so good compatibility to SVP as original avisynth. You can get memory leaks error.
does default's config (using older version of the softwares mentioned) provide a more specific outcome?
Default config was tested many times on many systems and we can guarantee what it must work without errors.
