It'd be super cool if we could also add in a check at the travis level for the makefile. There's a TODO on line 392 in build.xml for that as well 👸

        <!-- @TODO implement this upon deployment to d.o -->
        <!-- <drush command="verify-makefile" assume="yes" verbose="TRUE">
            <param>"${drupal.makefile}"</param>
        </drush> -->

We should also change the location in README.md

Follow-up to be performed as subsequent exercise (changes to build.xml, references to -core in README.md and elsewhere).
