That's a bit unfair to the modern compilers - there's a lot more standards to adhere to, more (micro)architectures, frontends need to plug into IRs into optimisers into codegen, etc. Some of it is self-inflicted: do you need yet-another 0.01% optimisation? At the cost of maintainability, or even correctness? (Hello, UB.) But most of it is just computers evolving. But those are not rules.
