Recently published work by N6LF, and much older work in the ARRL Antenna
Book differ strongly with that statement. In general, it is a waste of
wire to make radials much longer than the radiator itself, and according
to N6LF's recent work, it can even HURT performance to make them much
longer.

Strong agreement on that. Ground rods are for lighting protection. They
have nothing to do with how well an antenna works. And MORE radials is
definitely a good thing.
