Exactly, that's what I would think based on what I see (which isn't THAT much, admittedly).
Incidentally, I watched the Garage a Trois live video KEXP released today. Charlie Hunter plays a 7 string fanned fret guitar/bass tuned G-C-F-C-F-Bb-D. Scale length is 25" to 29". It's what works for him. Nobody says his bass playing doesn't sound good because it's a short scale.
