Yes, it is useful. I just learned about org-depend.el from this thread. So,
you may be right that the contributed packages are not known enough
and should appear in the documentation. 

org-depend does automatically what I was doing manually for some
months. It is especially useful for GTD. It reduces the list of open
next steps to a better manageable list without losing track.

Greetings and thanks
