The issue is not whether a fully operational ship could have dealt with this fire, but rather that the system obviously was very vulnerable, with no passive fire resistance to speak of.
Obviously periods of construction are periods on extra vulnerability, even the Notre Dame experience underlines that.
Similarly, many years ago the TVA lost a nearly complete nuclear facility because a workman using a candle to check for air leaks ignited wire runs in otherwise sealed channels.
I believe the nuclear industry changed its standards, but obviously the USN did not. Flammable wiring in a warship is a poor idea imho, even if it is cheaper. Non flammable or self extinguishing insulation is not new.
Counting on the crew to throw themselves into the breach created by poor specifications seems wrong.
