This time I haven't wrapped the response from the browser into any object. Giving the user response as it is. Do you agree with this approach?

In another module (Script) I have wrapped the response into custom-defined classes which I need to change as per your suggestions.

I think it looks great. In regards to wrapping request/response, I think we can iterate later and generalize rb/lib/selenium/webdriver/devtools/request.rb and rb/lib/selenium/webdriver/devtools/response.rb later.
