The Wiring Rules appear to most users as a series of rules to be followed so that an electrical installation is compliant. Yes, this is one of the goals, but safety is the paramount outcome of the standardised Wiring Rules.
Safety concerns are the driver of many of the amendments or additions that occur within the development of the Wiring Rules. The 2018 revision constituted a unique safety drive for implementation of RCDs, as an example. Many other parts of the revision were based around technological change and installation technique but at the forefront is the application of safety for the installer, the installation and the end-user.
Without SAFETY as the number one focus, the Wiring Rules would be lacking the necessary support for the future of the electrical industry!
