actually as of Sideview Utils 2.2.6, the Switcher module hides it's children as soon as it's initialized, and doesn't show any until the first context push hits it.
That makes it a lot better than it was in previous releases, although truth be told, it's still not perfect. And the reason that it's not perfect is that there's a small period of time between when the page loads, and when the Switcher gets initialized. The fix for that remaining problem will have to wait until Sideview Utils provides alternates to the base page templates themselves... (ie dashboard and search)
