The point is moot.  Pondering over this piece of code it suddenly
occured to me that the best solution is simply to remove it entirely ;)

This really is a leftover from an in-between broken implementation of
the interface, so the removal in this case bears no consequences.

If no further feedback on the patch series arrive, I'll repost the whole
stack tomorrow again.

Thanks again
