At least from beginning of 2012 we are keep educating users not to use CAR projects to develop/deploy server extensions as it fundamentally incorrect so we better to focus on clear solution instead of backward compatibility. Basically hosted artifacts and server extensions having two different lifecycles and need to be managed separately. Here Axis2 Modules, Class and custom Mediators, custom transport and message processors should consider as server extensions.
