One historical solution to this specific 'if debug' problem is called "runtime nop'ing". You know what another historical solution is called? Use a compile-time constant and let the damn optimizer optimize. (Virtually) no modern, widely used compiler would fail to optimize out `if (0) { ... }`. Also, why does M1 performance matter to Cloudflare's software? I kinda doubt their servers are on Macbooks.
