The other use case that a stack of patches workflow really fits is for maintainers of open source linux drivers (what I used to do). In that case, you're maintaining the driver in the upstream kernel, but you also need to get your code into Redhat's various kernels, SuSE's, Ubuntu's, and whoever else is the flavor of the day. All those guys have several kernels they support and they're all a little bit different. Porting over a pile of small patches is really the only sane way to go for that job, and for that, these kind of tools are a godsend.
