I am aware of the drafts you cited earlier, as Mikael mentions below the
existence of the same will not result in 6to4 being turned off
automatically or immediately.  This process will likely  take years.

Please note the goal here is not to make 6to4 great, like many others we
hope to see 6to4 use diminish over time.
