According to RB chart (https://rebrickable.com/parts/65574/bicy...llow-stud/, page bottom), there is a rather sharp transition in 2012 between 4719 and 65574. Most 3D meshes from LEGO use 4719 reference. The older ones (LDD) appear with plain stud/normal front stud, while the most recent ones (BIs rev>2) use hollow stud/reinforced front stud.
So I think we should correct 4719 with a plain stud, and create 65574 with hollow stud/reinforced front stud.
