My Look KG386 frame requires full length cable housing for the rear brake. I remember a recent discussion about someone's Pinarello frame requiring the same. I don't think it's a cheap bike thing. I've also never noticed much difference in braking from a segmented cable bike though that might have to do with me barely using the rear brake.
There are a few other options for sealing the cable on segmented frames besides Nokon. I've been using Jagwire sealed ferrules whenever I recable one of my bikes. Jagwire also makes a cable sealing kit which might give you what you are looking for:
