I've worked as a sysadmin for most of my professional career, around 25 years. Sure I've screwed up, but I've learned each time. Covering everything in bubble wrap to shield you from consequences of mistakes is counter-productive. All that happens is that you learn that there are safety nets and not to think twice about what you're doing. Also these tools are non-standard, so you'll expect them everywhere. Don't do this.
