I disagree: We cannot keep reminding implementers how defaults are set.

If one of the two dir attributes is absent a developer cannot compare them without knowing how to compute a default value. Telling
to check for the difference is all is need for that PR.

Look at this another way: You don't see the need to tell how the default value of state is obtain. Why would the default value for
dir would be different? In both case you look at the definition of those attributes and you know.
