The real reason these systems are not compatible with UK is the widespread use of ring mains which are not allowed in Europe. 

The same applies with a radial. If you have a mix of loads and power sources on the same final circuit, the MCB/RCBO/fuse can't necessarily detect and protect from an overload. 

The risk is nowhere near as high with a radial as the cable is not overloaded in the same way that a broken ring is. By definition you can't have a broken radial without it showing a fault such as sockets not working which isn't the case with a ring.
The potential to overload a radial is why the limit is set at 600/800W in Europe.
