Why should they? Honestly most of what we do simply does not matter that much. 99.9% uptime is fine in 99.999% of cases.

This is true. But unfortunately the exact same process is used even for critical stuff (the crowdstrike thing for example). Maybe there needs to be a separate swe process for those things as well, just like there is for aviation. This means not using the same dev tooling, which is a lot of effort.
