Go isn't inherantly more strongly typed. We could have just stuck with uint32 for the Go bindings following libvirt, but I made the concious decision to define Go types for all flags and use them in methods. Generally this isn't a problem as changing from uint32 to a strong type is backcompatible when we've had an unsed flags argument for a method. This situation where we changed the enum for flag for an existing API is thankfully rare, and the benefits of strong typing thus outweighs the occassional API breakage cost.
