To answer myself: The idea seems to be allowing to mux the monitor on
other character devices, be it one or more, be there also a dedicated
monitor terminal at the same time. But I still wonder if it is a
desirable behavior to have this broadcasting of typed commands and their
replies. Thinking more about this now.
