This one is better.  It also doesn't make sense to remove headlines
for plain text as they also has structure like numbers

  (defun rasmus/org-latex-ignore-heading (headline backend info)
    "Strip headline from HEADLINE if it has tag ignoreheading."
    (when (org-export-derived-backend-p backend 'latex)
      (let ((tags (org-element-property :tags
                                        (plist-get
                                         (text-properties-at
                                          (or (string-match 
".?\\(\\\\hfill\\|}\n\\)" headline) 0) headline)
                                         :parent))))
        (when (and tags (member-ignore-case "ignoreheading" tags))
          (string-match "\\`.*\n.*\n" headline)
          (replace-match "" nil nil headline)))))
