That 'minor' update collides with your theme, a fatal error eats the homepage, and your tracking links 404 during peak traffic.
Now you're debugging in production, bleeding conversions by the minute, with no clean point to roll back to.
A pre-change backup taken automatically right before every deploy is not paranoia, it's the cheapest insurance in tech.
If your rollback plan is 'frantically Google the error,' you're one update away from a very expensive evening. Fight me in the comments.
