I am fine with either approach, we can wait for 1-2 days to see whether
others want to say.  Otherwise the other approach actually looks better to
me in that it avoids SETUP->UNPLUG->SETUP jumps.

And then we wait to see whether UNPLUG can be dropped for either way to go,
perhaps starting from adding it into deprecation list if no objections from
the relevant folks.
