Is WithCapabilites on NewClient really needed or used?

[ibuildthecloud]

It doesn't seem like doing NewClient(... WithCapabilities()) will save the capabilities and send then in the Initialize. In initialize you need to pass the capabilites. So what is the point of putting the option in NewClient?

Capabilities: request.Params.Capabilities, // Will be empty struct if not set
