I think that the primary key would be useful for Bug 9717 'localuse recorded
for holds/transfers' -- we could record 'localuse' when the item is checked in,
and then update the statistics record to 'holdcaptured' or 'transferred' if the
check-in captures a hold or completes a branch transfer.

The statistics table is *very* slow to join borrowers or items against, because
borrowernumber and itemnumber are not indexed. It also caused a 12 hour run of
updatedatabase on site that had a large statistics table, when running the
upgrade that fixed bug 14598 (itemtype is not set on statistics by
C4::Circulation::AddReturn). This occurred on the 16.06.00.039 update.
