It's even worse when you forget to turn it off server-side. Slow deployments ahoy! This is the real problem IMO. Especially as capistrano's bundler module kills the log output when installing gems in the deployment environment, I bet a lot of people don't realise that 50% of their deployment time is generating docs, because they see no direct indication of this on the console output for capistrano.
