    # We are not adding a helper for capabilities here as the Account object
    # already has a capabilities property which is a hash and not the sub-list
    # of capabilities.

    # Somewhat unfortunately, we attempt to do a special encoding trick when
    # serializing `additional_owners` under an account: when updating a value,
    # we actually send the update parameters up as an integer-indexed hash
    # rather than an array. So instead of this:
    #
    #     field[]=item1&field[]=item2&field[]=item3
    #
    # We send this:
    #
    #     field[0]=item1&field[1]=item2&field[2]=item3
    #
    # There are two major problems with this technique:
    #
    #     * Entities are addressed by array index, which is not stable and can
    #       easily result in unexpected results between two different requests.
    #
    #     * A replacement of the array's contents is ambiguous with setting a
    #       subset of the array. Because of this, the only way to shorten an
    #       array is to unset it completely by making sure it goes into the
    #       server as an empty string, then setting its contents again.
    #
    # We're trying to get this overturned on the server side, but for now,
    # patch in a special allowance.
