I can't confirm that Henri Cartier Bresson said, "You don't need a machine gun to shoot quail", but anyone familiar with firearms and photography knows what Henri was talking about. It a finesse thing, not from the bunker thing.
Even in 35mm's hey day these cameras were few and for experts only. Leica made it's reputation on that wisp of a moment it was able to capture faster than any other camera.
After todays digital cameras run through their programed gesticulations they will take a picture, whether that moment is what the photographer intended is up for grabs. Marketing says the photographer will be happy with the image and the engineers will confirm it is an image.
It comes down to what it was designed to do and responsiveness is not a top design priority.
