Guessing you’re from the UK where you seem to have fancy pre configured sub boards. In Australia the standard and 99% of house installs are just hand wired with single wires from breaker to breaker and they’re twisted together and rammed into the bottom of the breakers :)

Germany, and I've worked on construction sites and in stage tech for a time in my career.
What you describe is... beyond awful and an absurd fire risk.

Lmao I moved from NZ to UK and the house wiring here has very often not been touched anywhere from the 60s-80s or so.
They are very slowly modernising here, but they seem to have a cultural resistance to change/modernisation; they're in love with the old days.
Very different to Aus/NZ where we're eager to get the latest stuff/NZ is often used as a test market.
That's bollocks or speaks for a completely incompetent electrician. Usually, you have three phase rails coming out of your GFCI that distribute the phases sequentially to each breaker [1] to avoid that scenario, as well as ending up with a tripped main breaker because the customer overloads the phase.
The only case where great care is being taken to avoid random assignment of phases is in event stage technology - you do not want your lighting dimmer packs on the same phase as your amplifiers because dimmer packs inject extreme amounts of EM noise, and you also have to take care to not put overloads on any single phase anywhere. However, it's questionable on how long this will stay relevant, given that most lighting load is moving off to LEDs.
