I didn't really follow the benefit of deleting your WIP despite the author being emphatic that it was important. In my view, if a change A I'm working on requires me to detour and make some change B, then a mandatory requirement is that change B really does work for change A. And not just I think it will work based on my memory of what I was doing, but I tested it and it really does work. My ability to predict all the details and impacts of a change are fallible, otherwise this unexpected detour wouldn't have happened to begin with. I guess that does point to a benefit - it decreases the desire to hold off on merging all the incremental changes until the full refactor is done. With the WIP there will always be one loose end to tie up before it is complete and you are really sure all the changes worked together. Without it, all you have is that the individual change didn't break anything so might as well merge even if there might be rework in the future.
