I have no idea. Given that (a) Apple doesn't really support hinting
anymore in macOS, and (b) there wasn't a problem report in the last
ten years related to this INSTCTRL feature I think it doesn't matter.
Maybe the OpenType standard's editor Peter Constable will contact
Apple to get a clarification w.r.t. my documentation issue report.
