I'm happy to see some diffusion of this circuit techniqueas a follower the input impedance can be very high while canceling most of the output Q hfe variation ( ccs bias input Q )
where it really shines is in a VAS stage with moderate emitter degeneration, the darlington like input impedance is combined with cascode like output swing linearity
