Idea is relatively simple yet requires some implementation effort. Repoman assigns ebuilds to three groups: 1. unmodified files, 2. modifies files, 3. new files, and outputs the issues in this order. This would help developers distinguish issues in the ebuilds they commit from issues in earlier ebuilds. Especially important when a particular issue should be fixed with a revbump.
repoman support has been removed per bug 835013. Please file a new bug (or, I suppose, reopen this one) if you feel this check is still applicable to pkgcheck and doesn't already exist.
