An interesting additional benefit here, is that rather than a brownout, you could just have a "soft cutover", where people can reenable the old protocols for two months. There's good reason for this: - People who aren't using the old methods can turn them off now and leave them off, benefiting from the new security change sooner. - People who need to fix something can temporarily repair their workflow at the time of their choosing. - People who need more than 24 hours to fix their workflow can re-disable the old methods to test that they are now good, at a time of their leisure, between today and March.
