1) Stage2 is intended as more than just fixes for stage1; It includes performance improvements, more codegen backends (direct x86/arm/wasm to avoid LLVM, C, etc.), will allow for incremental linking, hot reloading, and more.
2) The miscompilation in question is `if (false) else |capture| {}` not just `if (false)`. The latter is misinformation.
3) Miscompilations are conditional. Saying that the entire compiler is invalid given they exist is like saying rustc is invalid / can't uphold safety invariants given long standing compiler bugs allowing safe code to trigger UB / segfault [0] [1]. Both of such conclusions aren't true in practice.
