As others have mentioned, this really only works if you have a simple (and solid) deploy and rollback practice. Most people don't.

Given that, all it takes is one terrible deploy: shit goes way south and you're down for most of the day. Now you have the CEO standing around your desk nervously looking at you trying to re-federate the databases when you to realize a 7PM deploy is not all that bad.

>Deploying a major update when I’m not in work-mode is awkward as well.

I'm sorry, no. I love my family and time, too... But logging in from home for an hour or two in the evening to do a deploy and validation isn't that much to ask, especially considering most of our salaries. If you're that sensitive about it, come in late the next morning.
