What is the goal? Is there progress that isn't either turning a problem into not-philosophy or, as one of the OP comments put it, preventing bad philosophy from muddying the conceptual waters? (The latter still counts as net value to the world if the bad philosophy in question is believed by people without being told by bad philosophers. Maybe that happens a lot -- I'm not sure.)
I don't believe there's consensus in this, as philosophy might be the only discipline tasked with defining itself. Still, this is as good an answer as any.
