Well, some modern ships have. Supposedly much better at keeping speed in rougf weather

I suggest that if everything you say here is true then modern ships (especially warships) would have plumb bows and sterns. We know the age of the Dreadnought is long over.
Specifically, the negative trend toward CCA boats was because they were designed to fit a racing rule instead of seaworthiness, so many aspects of the design contributed to their poor seaworthiness not just overhangs. Contrary to your argument, most of todays offshore cruisers do have overhangs. They are not as big as more traditional designs but they are there. The overhang provides a drier ride not a wetter one. It is plumb bowed boats that have a tendency to drive through the waves rather than over them.
Regarding your claims of L/D ratios, your assumption that if the waterline length approaches the LOD then the L/D drops making it a boat as safe as an older boat with a higher L/D is flawed. The point is that as the boat with the shorter water line length (and consequently higher L/D) gets over run by a wave, the extra boat above the waterline comes into play and lifts the bow up. There is a reason why submarines don't have long overhangs.
The real reason some modern boats are built with plumb bows is for boat speed and interior room. A plumb bow boat better meets the demands for "Floating Condos" in a shorter hull than does the boat with graceful overhangs. They are also faster with longer waterlines. Proper modern bluewater cruisers still have overhanging bows if for no other reason than to prevent the anchor from flailing the hull and to sweep aside that log that you don't see....
