Yes, modern pads are more shaped but that can be done with both thicker and thiner pads. I have not compared all brands but of those I have a thinner/denser is a trend as you go up in price. Then there are the plush pads for those who prefer that. With reference to the pad linked above, here is a review by a guy who seems to prefer more padding.

"The Free Aero bibshorts have bright red padding, Castelli’s so-called “Progetto X2 Air Seat Pad” that combines a perforated upper foam layer with lower layers of multi-density foam and viscous inserts to achieve a balance between breathability and robust cushioning. The outcome is minimal padding that works well for racing and mid-distance rides (3-4 hours) that is extremely durable (I replaced my last pair of Free Aero bibs after a couple of years because the fabric was starting to fail rather than the padding) however I found myself looking to other brands when heading out for a long ride."

I'm not sure how he gets from "perforated upper foam layer with lower layers of multi-density foam and viscous inserts" to "minimal" without defining the word out of existence.
