No, you also need to parse #+SETUPFILE: keywords. You could also get
false positive within a verbatim block:

 #+begin_example
 #+title: something
 #+end_example

However, it is possible to write a specialized function to extract
only #+TITLE.

Another option is to cache results. See `org-publish-cache-set' and
`org-publish-cache-get'.
