As dicussed earlier this was designed for systems where you could set the pull-up resistance, like bias-pull-up = <600000>; would give 600kOhm pull up. In most existing systems that is silly, as they can't specify it, so they should be able to do just: bias-pull-up; as that is all they can do. If we have to cut one way, we should cut the former until such a system appears.
