This is a reasonable request, indeed. One (backward compatible) solution could be to extend possible values for NO-RECURSION argument, and allow functions on one argument (the current element) in addition to symbols. When the NO-RECURSION function returns a non-nil value for a given element, the main function from `org-element-map' is applied to the element, but not to its contents. What do you think?
