Even if you put prose in a warning message, it still doesn't explain the issue
fully. For stuff like that you need some properly written longer explanation
in the documentation.
Which I'm hoping we'll get eventually once the dust has settled down.
That's what the rest of this thread is trying to do but I haven't reviewed
yet.

This patch is a minimal stable fix to stop it from #MCing. The real stuff
comes later. It all has been discussed on this very thread.
