I agreed on not to have it as the default. I can still imagine couple of 
reason to have this option around. For instance, if the board designer 
decides to pull the bias voltage from outside of the chip completely, or 
like in my test setup when I feed the mic input from a headset output of 
another device, because I do not have a microphone around ATM.

But if you want it removed, I'll do it.

Best regards,
Jyri
