I agree. I think it would be primary structural support and a lot of space to move crew back and forth in an evacuation situation. Maybe in between structural support and power conduits there are small (like two chairs and a coffee table small) rooms for meditation, prayer, or a private game of chess by starlight. I think any use by crew would be more a case of clever humans making use of available space than space purposefully engineered for use by crew members.
This is an excellent point. The neck should have access tubes or (depending on which way the gravity "points") stairs of sufficient width to move groups of people rapidly from one hull to the other. That's gonna take up space.
