I don't like how these comments are spreading across the tree as
everyone copy-pastes them. On newer platforms, we settled on
setting bias-disable everywhere and there don't seem to be any
issues. Are these edits beneficial in any way?
FWIW I think this claim of lower power here is just preventing
leakage current from a floating pin..
