From where did you get this understanding? The Elisp manual says about
&rest:
"To specify a list of zero or more extra arguments, include the
keyword &rest before one final argument."
and
"The keyword &rest (which must be followed by a single
argument name) indicates that any number of arguments can follow."
i.e. the parameter after &rest isn't optional.
