Yes, Royce hubs come with a yellow leaflet explaining not to lace radially, clearly it was ignored. That said, if other manufacturers are happy with radial lacing on their 20 H hubs (including Hope), then what does it say about Royce shells?
Funnily enough I recall a rear DT 240 hub failing on the non drive side flange in one of their handbuild Mon Chasseral wheels, which you can't blame high tension for. Low tension is just as bad, if the spoke loses tension and the head is allowed to dig and grind in the hole at every revolution.
My comment re. Hope hubs failures and jumping is because I know Hope is very popular among downhill riders, trial and all sorts extreme bike users... I don't think you can experience such a catastrophic failure out of nowhere, "just riding along" so to speak... in the same way as carbon frames don't open up in half while you are riding, but they might do so if you crash against a bus
It's a flange with some holes, there is hardly any design secret about it... some lighter (thinner) shells seem to take radial lacing, including the 80 grams cigar shaped Taiwanese hubs
