As an independent observer, it seems the move to naming USN carriers after people flowed from the Forrestal & the JFK, and the decision to shift the state and city names to the growing fleets of SSBNs and SSNs. The old carrier names (battles and historical ships, and a few long dead people) went to the Tico cruisers and large amphibious assault ships. At the same time the USN was trying, in spite of political interference, to stick with its naming conventions, hence the Spruance, OH Perry, and Kidd classes.
That left the new carriers to be given deceased peoples' names, including presidents', instead of the SSBNs which used to get those (there was a George Washington class SSBN named Robert E. Lee, as an outlier example). The Carl S Vinson fitted with the Forrestal precedent, and of the Fleet Admirals, King, Halsey and Spruance were already taken when Nimitz was launched.
Doris Miller doesn't fit any of that.
If I was in charge, I wouldn't use live people's names, but then I'm not in charge.
Nothing wrong with the name Doris Miller. However, rumour has it that the next pair of CVNs will be named after those other two war heroes of Pearl Harbor fame - Danny Walker and Rafe McCawley
Walker and McCawley were in the Army, they named a tank after Walker [M-41] and the MBT-70 after McCawley, but the MBT-70 was cancelled.
