Title: Rework / simplify doc section on Bad or Missing Values

This follows off-list discussion with @hamogu about reducing complexity and opportunity for user error. It basically removes (in the documentation) the ability to set the `` replacement value, which in practice is not useful and sometimes harmful. There is now just a footnote discussing the *actual* capability.
