What designer? Small agile teams don't have a designer and a 'front-end guy' and a 'PM' and an 'architect'. They often only have one and in my case he (I) is also the PM (or PO in our case). Design-led software requires a designer. In large projects you might break this up into lots of different roles with trendy titles but they are all just designers, just as a database programmer and a graphics programmer are just programmers. Changing the design simply means deleting those methods and throwing away those unit tests. Which is wasted work, wasted time and totally dispiriting for a developer.
