The holes cost money, but the less copper you etch, the less etchant
you need. Overall, it's a one-time cost to design them in, and a
reoccurring cost to drill and plate the holes, but it's a huge cost to
re-do the board later if you decide you want 16-bit slots after all.
I'm sure the design engineers had to fight for those holes, but in the
end, it's not impossible to justify. The traces are going to go from
slot to slot to slot anyway (unless you group the empties on the far
end).
