Maybe I'm more risk tolerant, but I'm not so concerned about the compiler doing things that I didn't tell it to do. GCC and LLVM heavily rewrite code and it's generally rare to experience compiler bugs. Uglify/Terser very heavily rewrites JS, but you can still step through it with the help of source maps—sometimes without even noticing it's been compiled. Babel and others rewrite async functions into code that looks almost nothing like the original code (but runs in older browsers) and introduces a whole runtime library for executing them, but we don't even think about that.
