HarfBuzz does not do line breaking, so it has no way to know when to
apply such a feature. Justification support in HarfBuzz would be nice in
general, but I wounder how this can be done with the way HarfBuzz is
used now.

You can “manually” apply such a feature at line end if you already know
it, of course.
