Back when only handful commands that created commit and tag were the only users of committer identity information, it made sense to explicitly call setup_ident() to pre-fill the default value from the gecos information. But it is much simpler for programs to make the call automatic when get_ident() is called these days, since many more programs want to use the information when updating the reflog.
