It's not so much about ride comfort but about the ability of going over humps without slowing down. A car with much softer suspension will be more likely to hit the hump if going over it faster, even if at slower speeds it will probably be more comfortable. Obviously, it depends on what you prefer in your suspension, and the shorter travel of newer suspension will undoubtedly not be to everybody's taste. You're obviously right that a lot of the adaptation has been in the form of 4x4 proliferation, but there are of course also other reasons why people want those.
