Besides being a common idiom, for how many warts C++ might have, no one is rewriting LLVM, GCC, V8, JVM/ART and .NET runtimes, CUDA/Metal/DirectX, Unreal, Godot,.... into something else, RIR is not happening there.

People will contend themselves with "C++ the good parts", helped by clang-tidy, PVS, MSVC analyse, and move on.
