This new parameter will be used in the next commit. As adding the
parameter requires quite a few changes to plumb it through the call
chain these are separated into their own commit to avoid cluttering up
the next commit with incidental changes.

Nit: we don't typically write commit messages as a continuation of their
subject. Other than that this commit looks good to me.
