Right, I was trying to include the big picture as well, guess I let it
get a little fuzzy :(.

In the future, once we've got downtime deployments down to a fine art
(https://dev.launchpad.net/LEP/ReliableDBDeploys) we can look at
signficantly more downtime windows, but much shorter and more
controlled ones. That has a bunch of technical challenges involved in
it - for now we can remove a bunch of overhead that formed around the
concept of once a month, feature-including, high-risk deploys.
