I'm not sure the following is a bug, so discussing on es-discuss first before filing one.
I agree that during the meeting we explicitly discussed MAX_SAFE_INTEGER but not MIN_SAFE_INTEGER, which is why I wrote "presumably" in my previous message. But I think it violates both consistency with the rest of the API and the principle of least surprise to omit MIN_SAFE_INTEGER. We should just include the obvious definition of it, as in my pseudocode above. If no one disagrees, I'll file a bug. Thanks.
