It seems that the standard stud meets the criteria of 2.0D stud engagement so it is difficult to see why a longer thread will provide much benefit.

I believe one of the main drivers behind this was to eliminate the need for careful
control of the axial position of the studs on installation. Instead of "Install to an exposed height of xxxx mm," you run them in until they bottom; the install height is automatically controlled.
I find that appealing from a DIY perspective; one less thing to worry about.
