I am listening, but I am not a compiler backend dev. :-) I recommend filing a bug about the missed optimization opportunity through the C++ tab of Developer Community at https://developercommunity.visualstudio.com/spaces/62/index.html .
(I've been busy filing optimizer bugs against MSVC and Clang/LLVM while working on charconv; filing bugs with clear repros is the best way to help toolsets improve.)
Thanks,
