Can you add a post-processing hook? A simple text replacement might be enough.

Or modify the textarea function to understand :wrap - not sure whether Nicolas
would accept a patch though:

--8<---------------cut here---------------start------------->8---
(defun org-html--textarea-block (element)
  "Transcode ELEMENT into a textarea block.
ELEMENT is either a src block or an example block."
  (let* ((code (car (org-export-unravel-code element)))
         (attr (org-export-read-attribute :attr_html element)))
    (format "<p>\n<textarea cols=\"%s\" rows=\"%s\" 
            (or (plist-get attr :width) 80)
            (or (plist-get attr :height) (org-count-lines code))
            (or (plist-get attr :wrap) "on")
--8<---------------cut here---------------end--------------->8---
