Fair enough. But then I have a question about the
change. It increases the window from 400 to 402
years. Is that part of the change needed? As I understand
it, it's to avoid coalescing (say) a 399-year run
of a rule to an adjacent one-off that *happens*
to look like the extension of the rule. But is there
really any harm to that? Such coalescing is what we
already do, when preparing the input data.
