From the data I've seen, I agree with you that they lose effectiveness at low frequencies. But I also see significant improvements through most of the band, so I think they are definitely a good thing. It costs more to add them, they are an added complexity and that makes costs go up. But I think they're worth doing. I just wonder if there are more technical benefits than reducing harmonic distortion and improving inductance linearity. Seems like I remember someone saying something else they improved, but I don't remember what.
