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?
Regards,
