Of course it has. But you need to realize that even Gerber doesn't
have advanced information you need for more complex designs (i.e PCB
dozens of layers with different type of impedance, etc). For that you
need an EDA with IPC-2581 support that even Eagle (AFAIK) doesn't have
and many other commercial EDAs also don't.
