It's a great way to have an unfixable mountain of tech debt. See, Kanban only works when the focus is on quality. It's the main secondary premise of the original Toyota approach of Lean which spawned Kanban. Note that it starts with minimizing waste (in programming, tree breakage or waiting on tests) and secondly minimizing overloads. The philosophy is kaizen, continuous improvement. Sacrificing quality is not an improvement, Toyota itself started by breaking process into quality assured steps to fight waste due to rework. Otherwise anyone can push undone paper tickets over the wall and that's not the point.
