I guess not having this enabled by default might be problematic. Imagine some test cases added without sorting at random positions in one patch and then sorting them in another patch as some more test cases are added. This would also move cases added in the first patch. (I assume the idea is that ultimately we want keep all MC test files sorted at all times.)
