I wouldn't remove it.  This manual is an extended tutorial of the
Emacs Lisp language, so it doesn't necessarily include only the
frequently-used functions.  We must trust the author of this manual,
who was a great expert in teaching Emacs Lisp, that his decision to
include this function had a good reason.
