Great title. I feel like in some sense we've lost our way with compiler design. Languages do not help us write code that require minimal optimizations to run fast enough on most workloads. Instead, we overoptimize with -O[23] everywhere which slows down our development process and makes all of our code inscrutable. Better would be a faster -O0 experience and good profilers/observability so that we only optimize the hot spots (which could mean isolating specific subcomponents and compiling only those with optimizations on). Of course it's much easier to just globally turn on release mode and optimize everything whether it matters or not. This both slows down the development process considerably and leads to bizarre issues like this.
