I think the point is that *if* you have an IR - or are training for one - and no NVFR rating then doing the small additional bit of flying will then let you use NVFR procedures- without having to hold the NVFR rating. Otherwise NVFR procedures are a no-no.
I advocate getting the NVFR rating even if you'll get an IR. Using an IR, NVFR procedures are only allowed as long as the instrument rating is valid. Let the IR lapse and so does NVFR procedures until the IR is renewed.
