4mm half of circuit on 32a mcb

Quite handy for largish buildings. Run a 4/6mm from the CU to where the ring is needed. Great for confusing the youngsters.

I think we used 6mm when we got around to rewiring the brothers 4 floor + basement house. Both of us electricians, it only took three years to finish.

We used to do this in labs for bench sockets when I was an apprentice. 6mm to a 30A switch above the bench, from there a ring of sockets for the bench.

LOL, like a cobblers children always go worst shod (or the phrase is something like that)!

Im sure there is a regulation about downsizing requiring a protective device even if the upstream protects the smaller conductor.

No, the regulation requires protection at every reduction in ccc, the conversion to a ring from a radial does not represent a reduction in ccc, just the csa of the cable.
