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 ?
