While what you are saying is _technically_ correct, the details paint a very different story.
Linux only requires GCC 5.1, which was released *nine years* ago. Versus rustc 1.78, which only landed *four months* ago.
(Or you could use LLVM/Clang intstead of GCC, that requires a ~2.5-year old version (13.0.1)
