Perhaps, but I don't think there's a reasonable case for considering
them equal, either. In the other places where obviously-different
values compare equal, such as zero versus minus zero in IEEE floats,
it's widely understood as a gotcha.

Even if you'd made a case why we should consider them equal,
those would be very good reasons not to change behavior that's
stood for 17 years.
