Section 31 marks the extreme end of "sensible paranoia." The broader concern is that the Federation is surrounded by potentially hostile powers. The Klingon-Federation alliance is critical to peace in the Alpha Quadrant, and Klingon leaders need to feel that their empire is still the stronger military partner. Starfleet gains by looking less powerful even when Federation industry could support a much larger force. Building adaptable hulls without visibly fitting them for combat reconciles alliance management with strategic caution, provided those ships can be converted before a crisis is lost.
