There is. Often in maps that we produce, usually hydrographic ones, we'll
want leader labels on one side (right) showing scenario 1 and labels on
the left side showing scenario 2, for example. Most of the cases I can
imagine for limiting leaders to one location are primarily labeling linear

The second was what I had in mind, keeping all the labels as type leader
and going right to drawing that way even when not strictly needed.
