This patch is specifically trying to reduce > the need for those. I have run into situation where I find the unused argument warning for `-nostdlib` is inconvenient (musl clang wrapper), but I can think of users who actually want to the diagnostic. I am concerned that the decision suitable for your use case may not be desired by other groups. This is why I'd like keep suggesting `--start-no-unused-arguments`: it encodes the intention clearly and cannot get in the way of others while achieving your goals. It's just longer, less ergonomic.
