Even if J..F and J..I were of the same hop-count, there is no
fundamental reason to choose one over the other.
What is "best" at that point depends on what the user wants to see.
- Luis's case that started this thread may want to favor v3.4 if
only because that "sounds" the smaller, even though v3.4 and v4.0
in the illustration cannot be compared.
- I think the "closest" we have had is primarily a heuristic to
favour the result that is textually shorter.
- And as I alluded to, "which one has the earliest timestamp?", is
another valid question to ask.
In other words, there is no single "correct" answer, once you have
multiple canidates that are all valid from topological point of
