Up to and including Blender 2.79, when you creased edges, stacked Subdivision modifiers had a different effect on the creases: the first subdivision modifier kept the crease fully sharp, while a second subdivision modifier fully subdivided the output of the first subdivision modifier, including rounding of the creased edge.
But in Blender 2.8 a second subdivision modifier keeps the creased edges fully sharp. The 2.7x approach allowed the rounding of creased edges to be controlled by stacked subd modifiers. This is not possible anymore with the 2.8 subd modifier approach.
Please bring back the old approach, or add a ‘Round creases’ option that can be activated in a second Subdivision modifier. Modeling using creases and stacked subdivision modifiers is a powerful workflow for hard-surface modeling, avoiding the need for lots of extra edge loops.
