What Happened After Google Retrofitted Memory Safety Onto Its C++ Codebase?

Google's transistion to Safe Coding and memory-safe languages "will take multiple years," according to a post on Google's security blog. So "we're also retrofitting secure-by-design principles to our existing C++ codebase wherever possible," a process which includes "working towards bringing spatial memory safety into as many of our C++ codebases as possible, including Chrome and the monolithic codebase powering our services."
We've begun by enabling hardened libc++, which adds bounds checking t
