Review comment:
StoreEngine delegates the work to a `Compactor` implementation, where
`DefaultCompator`, the default Compactor implementation, uses this one to
create the file writer. So that's why we say it's the "default" method.
Alternatives compactors may not use it, like the `DirectStoreCompactor` that
implements its own logic that creates the file on the store directory, rather
than under temp.
