I really enjoy these old 'boatanchors'. I've spent many pleasurable hours listening to distant finds with a longwire antenna.
Some BFO oscillator circuits do use a wire that goes 'nowhere'. It is called a 'gimmick' and acts as a capacitor to couple it to the circuit in it's proximity.
'Tickler' coils also go nowhere on paper, but being in the field of an adjacent coil, they pick up influence from that coil. They are all methods of coupling.
