Many of my customers are in an industry with a huge C++ code base and it's all under active development. Safety certification requirements are onerous and lead-times for development are long: many are now experimenting with C++17 and C++20 is on the long-term horizon but not yet a requirement. Because of the safety certification requirements and the fact that the expected lifecycle of the software is the order of decades after their products have been released, changing any lines of their code for any reason is always risky. Lives can be at stake.

But this is a multi-billion-dollar industry. If you're working on scripting a little browser "app" for a phone things may be different.

Is there a lot of manual work for getting the new certificate? E.g. is human rewiewing the code? If not, someone should build CI pipeline for the certification process.
