    Too late once they've announced them

    As with v4 if the herd doesn't stay together on policy then once some
    have accepted the rest get picked off one by one as their customers
    complain (I've watched a smaller ISP try filtering v4, sucks to be
    them)

    If there is to be a deaggregation limit it needs to be universal and
    set up already so people don't try to annouce.

    Doesn't work is a better argument than some will try and stop it
    working. Game on.
