 Unless this had been deliberately omitted for performance reasons?

 A minor change to the {{{Walker}}} class would provide the total number of
 children {{{$this->total_children}}} for the current element scope from
 within the {{{display_element()}}} function.

 Currently a custom walker must be used and include an extension of
 display_element() for each {{{X_Walker}}} class where this information is
 needed.

 Patch attached.

 This change; for example could provide information to display the number
 of replies to a comment in an extended template of
 {{{Comment_Walker::comment()}}}
