org-sparse-tree using Lisp predicate?

Is there functionality to build a sparse tree (as with org-sparse-tree)
using a predicate from Lisp code? I want something like org-map-entries,
but for narrowing/sparsing. Diving through the code, I think (org-scan-tags
'sparse-tree (lambda () … )) might be what I want, but am curious if anyone
else has suggestions from working that use-case.

I think I figured it out. This contrived example is simplistic, but it does
what I want:

(with-current-buffer "something.org"
  (org-scan-tags 'sparse-tree '(not (null (org-entry-get (point)
"some_property"))) t))

Would be a nice built-in sibling for org-map-entries :)
