Review Comment:
> That deep copy is error-prone.
Did you mean we shouldn't send ClusterConfig as an argument to `builder` ?
If so, I can remove this method (i.e. L168). But that means we have to
explicitly write all setters if we want to copy a ClusterConfig to a brand new
one.
And I'm not sure why this is error-prone. Would be appreciate if you can
share more 😃 .
