These blame to the following commit:

  commit 39a3f5ea7c0352a530338d30d4e618f6b4db84e4

      Customizable error handlers
      
      This patch makes the usage(), die() and error() handlers customizable.
      Nothing in the git code itself uses that but many other libgit users
      (like Git.pm) will.
  [...]

So apparently the intent was that they would only be used from outside
Git.  I don't know whether anyone still plans to do that, but they're
certainly not "just" unused.
