An ex-ARM engineer critiques RISC-V

I don't think C screwed up. C's objective was to standardize a set of practices based on what the hardware of the day was capable of. If they had pessimized performance on one architecture because it failed to provide efficient checked overflow (or any other feature), then C would have never made it to standardization.

ISO C is therefore a three-way compromise between three communities: Software authors, compiler authors, and CPU manufacturers. You will naturally end up with some decisions that dissatisfy some members of each.

Better would be to say that the C standard committee screwed things up by refusing to address a lot of issues over the last 35 years.

Not really, they have addresses pretty much all of the issues. Now, you can argue that they favored compiler authors when doing so, but they have consider the problems and done things in response to them.
