The alternate G3 arrangement could support a larger superstructure and put still more distance between machinery heat and the magazines. That spacing would make the ship more sectional in everyday use. Crews could work on engines aft without becoming entangled in gun and ammunition systems forward. Less interference between major systems improves maintainability and gives failures fewer immediate paths across the ship. Ships of this size could also be expected to receive modernizations, so internal room and separation would remain valuable long after commissioning.

Internal separation made maintenance and resilience easier
Separating guns, magazines, and machinery would let crews work on one section with less disruption to the others and leave more room for later modernization.
