This must be one heavy half shaft!

While the half-shafts are fairly highly stressed, they are quite up to the job. Failures of properly shortened shafts are extremely rare, and if the shafts are designed correctly, they don't fail catastrophically. The u-joints that Jag uses are heavier-duty than any that Corvette ever used, even in their old 427 cars, and Chevy felt they were reliable enough to use all the way up to the C5s. Weight-wise, I doubt whether our shafts and joints are significantly heavier than a CV system.
Chassis weight loads are only about 10% of drive loads and actually decrease on the outside wheel during cornering to near zero.
