I imagine that the purpose behind a bare repository is really just to provide a repository into which objects may be pushed and from which objects may be fetched, and that's it; it's sole purpose is to act as a point of communication. Cloning a repository with --bare is meant to simplify the task of setting up a bare repository with some initial content.

Fortunately, we're talking about the history of a revision control system. I found this with `git blame -L70,76 71821351^ git-clone.txt':

      clone: do not create remotes/origin nor origin branch in a bare repository.
      
      It is simply pointless, since no merges will ever happen in such
      a repository.

That certainly corroborates the limited purpose of a bare repository.
