Browser-only VNC (RFB) viewer enablement

What is the benefit? Why is this valuable?
The use of the Qt VNC Server comes with an expectation of a zero-deployment viewing via a browser. At the moment, there is no self-contained solution provided by Qt. Since the recent release of the Qt HTTP Server such a self-contained solution became possible.
What are common use cases?
The user expects to "connect" to the (Qt) UI vian an HTTPS URL with a standard browser and view the content of the screen projected by the Qt VNC Server
Technical information
