Apparently that user restriction is actually tested in two places in the codebase. Having the restiction on your user will prevent access to the Android version easter egg. It will also prevent access to debug features in whatever "DocumentUI" is. I suppose third party apps could also test for it, and do things with it, but is is really just intended as a joke.
