I agree with Pace, I never file anything but I on my plans and never have a problem getting them accepted and I fly out of a private strip.
I have been dumped out of the bottom of CAS a few times but recently have started to refuse the descent until I am ready and not had problems with that. If it is a nice VFR day then I don't mind but when it's like soup I need to be close enough to home to know if a VFR approach is possible or a diversion is needed and that is much easier when still in the IFR system.
