I can see how that's less than ideal, yes.  I'm not that interested in
the :forced option, honestly, other than not breaking it.  I only
brought it up because I used some of its concepts in my :depends-on
fix.  Loosely, if one of a component's dependencies required some
action, then that action becomes forced for the component.  I'm not
sure I did that in a way that is compatible with how :force is
supposed to work.

Could you comment on that issue?  I.e., whether :depends-on is
supposed to work the same way for modules and systems as it does for
files?

Thanks,
