There is no pronouncement about dry suit material type. In general, it's recommended to use a laminate suit, because they allow more flexibility in water temperatures and because they dry quickly for travel.
One of my instructors, former GUE instructor Joe Talavera, put it in a way that made a lot of sense to me. There are things that impact your team, and things that don't. Dry suit material only impacts the team if slow drying has an effect on logistics. (Although full neoprene suits can have an impact on team function, if they lose too much insulating capacity at depth.) Whatever material dry suit you buy, you have to have enough mobility to reach your valves and manipulate bottles.
