Most of the time, however, they are all still connected to one phase and one fuse, so it is not any different. Unless, of course, you run more into the cabinet, but that is rather not done with conventional wiring.
First of all, 3600 watts must be reached - the load is more of a secondary argument and often does not apply. Pure convenience and aesthetics are, in my opinion, the more accurate arguments.
Safety is also an argument, because especially power strips that lie around somewhere can quickly get dirty or moisture can get in, especially in the children's room. I once saw one smoldering. It definitely would have caught fire without a fuse tripping. Luckily, I noticed it.
