Yep, I think this one makes sense. I would be a bit curious to see how
often reuse actually kicks in for you with the current code. Back when I
worked on this topic in 2015, it was kicking in for us almost-never (at
least for big repos like torvalds/linux that we were interested in
measuring), but that's because we were packing all of the forks together
(and still do). The earlier heuristics made no sense for that case.

I don't know if it's really worth spending a lot of time trying to
collect data, though.
