I have to say, I'm a little baffled by this thread. As I understand it, from the very beginning, OF has been conceived and designed as a GTD app. It came from kGTD. Sure, other folks are welcome to use it, but it's primarily meant for implementing GTD. If you don't want to use GTD, there are plenty of other productivity apps out there for you to use instead.

That said, I can't see what good an "in progress" context or setting would be. In GTD, "waiting for" is the context that handles situations like "I made a phone call and now I can't do anything else until that person gets back to me". The whole point of GTD is keeping track of all your open loops; either a task is completed, or it isn't. It's pretty simple in that way. No need to muddy the waters with a third state. If you need one, great, but that's not practicing GTD, and thus perhaps OF isn't the app for you.
