Except for on super-weird case involving FS level corruption, I've never needed these targets since the cut-over. cleandepend may be required in some weird edge cases, but it's rarely needed that you can omit it most of the time. It used to be required whenever the dependencies changed as part of the build. That's mostly, but not entirely, fixed today. Warner
