Reviewing [this code](https://github.com/googleapis/gapic-generator-go/search?q=New%25sClient), it appears that client constructors include the names of their associated services. But [here](https://github.com/googleapis/gapic-generator-go/blob/a6c0c818b67975c14ebab052c7bf37d45548baff/internal/gengapic/doc_file.go#L100), a comment in generated `doc.go` refers to an initializer named `NewClient`. Is that an obsolete reference?
