If the source impendance at dc is 10k at dc a bias current of a few microamp produces a dc offset of tens of millivolts which may be an issue if the signal amplitude is low and has a low slew rate.
Jeez, Bruce, it was nothing but a thought experiment to illustrate why an amplifier's DC input current is not a reliable proxy for input impedance It was not a suggestion for how to design an amplifier input. And that should have been obvious to you -- I'm sure it was to everyone else.
