/cc @zendesk/zendesk-radar

### Steps to merge
 - [ ] :+1: of the team

### References
 - https://zendesk.atlassian.net/browse/RADAR-422 (mainly this)
 - https://zendesk.atlassian.net/browse/RADAR-419

### Risks
 - Low: documentation is still incorrect, and misleads users
why remove this? Can we not see this if we do Minilog.enable() on the console? Maybe that should be specified too. Minilog.enable() to see all the logs.
