I still don't really understand why this wants to be a separate patch.
The warning text emitted by the previous patch (whatever text we agree
on) will be nonsense until this patch is applied.
If this patch cannot appear before the warning is introduces then there
is no correct order for patches 4 and 5 (which implies they should be the
same patch).
