PHPUnit 4.8, which was released today, is the last version of PHPUnit to support PHP 5.3, PHP 5.4, and PHP 5.5. I think that DbUnit should follow PHPUnit's lead and only support PHP 5.6 and PHP 7 in a DbUnit 2.0 release that should happen within the next two months.
Requiring a newer version of PHP would make new features such as #167 possible.
