Different world, but in the USA if you switched off the transponder and quit responding to radio calls you would have some F16 escorts pretty quickly.
Not particularly relevant but that is the case for the majority of US airspace as well. Painting with primary radar is a seldom used backup now and is only effective for a discrete distance around the radar. Transponder systems are the primary radar system worldwide.
