    You can also argue that the earth is flat. It's just that some
    arguments have more basis than others.

    In other words, you don't deny the problem. Instead, you work around it
    in user space.

    Better to fix the API. The kernel has more information than user space
    and can do a better job. In the kernel, the problem can be fixed once
    and for all, not over and over again in each different wrapper library.
    It's not even as if the change would break programs correctly written
    to the old API, not that we particularly care about programs written to
    the old API.
