That makes for the thought experiment: what would the cost be for retaining the per-time properties? Essentially one would have to keep a copy of the grob-properties for each breakable column until the final breakpoints are established. How useful would that be? How expensive would that be? Frankly, I am fuzzy about either. Could it be used as a basis for something like line-break dependent accident rules? Could it provide a more user-accessible way of doing things than \alterBroken ? -- David Kastrup
