The problem described in the rsync section in gitcore-tutorial:

  "can produce unexpected results when you download from the public
  repository while the repository owner is uploading into it via rsync
  transport. Most notably, it could update the files under refs/ which
  holds the object name of the topmost commits before uploading the
  files in objects/ - the downloader would obtain head commit object
  name while that object itself is still not available in the
  repository."

I only thought about git itself uploading into and downloading from the repository with push and fetch, respectively. And wondered where the problem with the order of refs and objects was. But I just realized, it can of course be uploaded with plain rsync, too.

Yes, this is the answer to my question. I thought maybe it's not deprecated anymore, because the only place where it is called so, is gitcore-tutorial.
