And some critical rust issues for games are not dealt with: on tiny glade with the devs did hit a libgcc issue on the native elf/linux build, and we did discovered that the rust toolchain for elf/linux targets does not support the static linking of libgcc (which is mandatory for games, any closed source binary). The issue is opened on rust github since 2015...

But the real issue is the game devs do not know the gnu toolchain (and llvm based) does default to open source software building for elf/linux targets, and that there is more work, ABIs related, to do for game binaries on those platforms.
