When you do a shallow clone, no files would be present. However when doing a full clone you’ll get a full copy of each version of each blob, and what is being suggested is treat each revision as an rsync operation upon the last. And the more times you muck with a file, which can happen a lot both with assets and if you check in your deps to get exact snapshotting of code, that’s a lot of big file churn.
