There seems to be a low tolerance to the construction disruption, especially to adjacent businesses and residents. Cut and cover also had high cost of moving infrastructure. I also wonder whether there's some relationship with the speed of construction - in NYC, ripping up the whole street to build a Subway was perhaps more acceptable if it's done in a year or so. One note: new cut and cover projects tend to actually use cover and cut: first the walls are built underground (often piledriven), then the top is covered with a concrete plate, then the Earth dug away from below. This minimizes the surface disruption.
