I have a backline distro system that has an RCD per socket (10mA) to try to ensure that there is some discrimination, each outlet on the main distro has a 30mA RCD, and the 63A socket the whole mess plugs into is usually on a 100mA Time delay RCD.
With competent modern ones, there is pretty much no such thing as a nuisance trip, if it goes there is something wrong.
The only time I have seen a leakage problem take out an RCD was with a whole pile of LED lighting, which was somewhat notorious for it, we put an isolating transformer in the way, problem solved.
If you set up the distro so that there is no easy way to bypass the things then you do not get tempted when the pressure is on.
Expensive, but what price a life?
