Personally I don't see the need for an automatic updater at all.
Unless there is something specifically broken in your UI preventing you from playing you can afford not to update your addons for a while.
There's also a number of ways you can use to manually update your addons. No it doesn't take as long as people think. Takes me 15 - 20 minutes every 2 weeks , usaully on a maintenance night or if I'm bored on wow.
