IMHO, the optimum design is to adhere to the "separation of business 
logic and GUI" paradigm (that in fact is not even created with embedded 
applications in mind) and do the program in a way that it has a switch 
to  compile it with and without the GUI. So at best the version without 
the GUI should use an infrastructure ("Interfaced" / "Wideget Set" / 
"Platform") that does not force a GUI binding.

This is exactly what I have been planing regarding the bad luck 
regarding any kind of active NoGUI Widget Set.

I don't think so, and I don't see the point. For me the question is 
whether an application can start without an interface to a GUI 
infrastructure (such as "X") is found in the system.
