Early Status graphite necks were completely rigid and needed no truss rod, they popped out of the mould with exactly the right amount of relief and never moved no matter what gauge strings you put on it.

Surely, some of them must have moved over time (due to design flaws). I remember reading that some of the old Zon basses, made in a similar manner, were designed to be perfect out of the shop. And that was that, as there was no adjustment in the neck. Some gave years of good service before a 'shift' in the neck rendered them unplayable. I can't remember what the outcome was (knowing Joe Zon, probably some form of recompense), but there was evidence there of this occurring.
That said, I've owned an old 80's Status Series II. The best sounding Status basses ever made, I think.
Furthermore, what does 'stiffness' in the neck really mean other than tuning and setup stability? Take, say, a Jaydee Supernatural. Renowned for having thin, floppy necks that shift as the wind changes. Do they sound floppy? No!
