One of the biggest barriers is part 91 operations with no written SOPs. At least with an SOP pilot X has something to "fall back on" when pilot Y is 30 knots fast on approach. The better departments natural arrive at the realization that it's better to fly the book and that the book requires annunciation of a deviation along with corrective action.
