Agreed.  There are already different such things distributed with Emacs:
.dir-locals.el is one of them.  CEDET has its own notion.
As mentioned .dir-local.el often acts as a project root, but it can also
appear in sub-directories of a project, so it's not sufficient.
It should at least be augmented so that some .dir-locals.el can be
flagged as "non-root".

If the only need is to figure out the "root directory of the project",
then maybe a simple solution is:

   (defvar project-root-predicate
       (lambda () (file-exists-p ".dir-locals.el")))
   (defun project-root ()
     (locate-dominating-file default-directory project-root-predicate))

where packages can (add-function :until-before (default-value
project-root-predicate) <mypredicate>) to recognize other "tell tale
sign" of a project root (e.g. a Tupfile).
