Working through adding NOT_PREFERRED to allocation explain and these refactors help me reason about it better. |

There was a problem hiding this comment.
Can we either assert the boolean result here is the opposite to canRemain() or delegate it to canRemain(), i.e. return canRemain() == false? It would be nice to prevent these methods to go out of sync for any reason.
