Yes, that's a great idea. I've added it to the patch.
One caveat: this patch does not implement recursive checking of included
files (i.e., included files that include other files), but this could be
added in the future.
Thanks,
Matt

Subject: [PATCH] Speed up publishing by caching included file data
* lisp/ox-publish.el: (org-publish-cache-get-included-files): New function
(org-publish-org-to): Use new function
(org-publish-cache-file-needs-publishing): Use cache instead of
visiting every file in a project.
Org-publish can now quickly determine a) whether an org source includes
other files (either via #+INCLUDE or #+SETUPFILE) and b) whether those
files have changed. This speeds up the publishing process and makes
tracking of changes in included files more reliable.
