That makes no sense, IMO.

I think the last line is misleading, in the “Application interface” it
specifically says:

  The application may rely on the user to apply this feature (e.g., by
  selecting text for a change to all-caps) or apply its own heuristics
  for recognizing words consisting of capitals.

Are you going to implement such a heuristic in HarfBuzz?
