    I think it's *much* harder to carry legacy things around in an old tree
    that almost nobody even uses any more (probably not true yet, but for most
    of the main developers, I bet it will be true in a year). Especially one
    that just duplicates 99% of the stuff.

    There really isn't that much legacy crud. There are things like random
    quirks, but every time I hear the (theoretical) argument about how much
    time and effort we save by having it duplicated somewhere else, I think
    about all the time we definitely waste by fixing the same bug twice (and
    worry about the cases where we don't).
