I'm not seeing why you're making such a big fuss over this - IMO its not such a significant breakage. Esp since very few realtime apps will require such large amounts of time to ever run into the throttle.
If their usage is 95%+ cpu they must have magic WCET estamates - or like in this case, be a benchmark app which IMHO just abuses the real-time class.
It's like running your real-time code on a 5% slower cpu - if it runs correctly on the 5% slower cpu, it will run correctly here too.
Note that correctness from a RT pov is making your deadline.
