GUIs have different requirements. They display a finite number of views on directories, so for them it is fine to not have hierarchy watching capabilities. A sane dnotify API should have the ability to watch hierarchies. And it should not even be that much hard to do, since you can just backtrace the the point where the change happened to see if there are watchers on the parent directories.
