We could. I'm not against it. I just wonder if it's going to be useful. A typical deadline is calculated as `now + delay`, where `delay >= 0`.

On the other hand, that issue with `i.minus(Duration.between(Instant.MAX, i)`, which I [described][] here yesterday, makes me think that `minus` might be useful if only for that.
