It is by design. The core argument for doing it is that '-' might have
type-dependent semantics that would not be reproduced by negating first
and casting afterwards.
Even if you could convince people that that concern is baseless, there
would be a backwards-compatibility problem. For a comparison point,
note the hurdles I had to jump to persuade people that we should change
the precedence of comparison operators --- something that has clear
support in the standard, as this change would not.
