For example, some compilers offer options such as -ftrapv vs. -fwrapv that can fine-tune whether abs(INT_MIN) behaves a specific way, whereas POSIX unilaterally requiring a specific behavior is at odds with that ability to fine-tune behavior. Thus, this is a valid argument worth reopening the discussion on this bug, and limiting the changes to JUST making int and friends have twos-complement representation, without also requiring (as a much tighter restriction than C) that abs(INT_MIN) be well-defined.
