I think that "stalled" should work just as it does, but that there should be an additional filter for projects without any actions defined. Does this make sense? Am I the only one who thinks this could be helpful?

I'm with you. I wrote a script that checks for projects and action groups without next actions. It's available here.

The script adds the text "Missing NA" to the end of each project without a next action. You can then use the OmniFocus search field to filter down to those projects. It's not as graceful as built-in filtering, but does the trick for me.
