From a layman's perspective, it sounds like they shot themselves in the foot somewhat by taking modularity to a logical extreme — building a highly generalizable bus system that would support connections of any kind of component on any part of the device. I wonder what gains would come from relaxing that requirement, so a certain sector is always reserved for a camera, another for a battery, etc, one for each component that everyone is obviously going to want on their phone but might be upgradable over time. The idea of being able to attach a Geiger counter to your phone is intriguing but that was always going to be a niche within a niche.
