As for the motivation for the change, it's based on the idea that the current `round()` behavior is some kind of bug. In other words, the behavior of HALF_UP `0.285` to become `0.29` is itself a bug. To be honest, I'm completely neutral on this. I believe that this is a matter of will and what we want to do. As far as I know, Tim and Gina want change on this issue. I don't want to ignore such opinions and move forward with implementation, so I would like to hear a wider range of opinions. I have created this RFC in order to determine "our intention" once again.
