"I think we'll just see folks using the unstable APIs and then complaining when we remove them, even though they know upfront that these APIs will go away."

That problem would be much worse if some modules were simply marked "experimental" in the doc, rather than put in a separate namespace. You will see people copying recipes found on the internet without knowing that they rely on unstable APIs.
