    Neither - as they evolved over time, the rules were revised to more
    clearly state how to handle certain edge cases and to remove language
    that could be (and had been) misinterpreted. In other words, the
    statement of the rules has improved. Now that we have a field-tested set
    of rules, it's of course easy to re-write them, because you can be
    certain to know what they mean.

    Perhaps by going your route, we would have arrived at the same result.
    Who knows. That's the difference between theory and history. History
    takes one, and only one of the possible paths to get to a result, and it
    doesn't give a bit about whether that path was optimal.

    If you'd been a contributor then, history might well have proceeded
    differently.

    Cheers,
