An increasing amount of AWS EC2 dataplane (Nitro firmware/software) is using Rust.

We hit this issue too, and our solution was to go busybox-style with binaries. One binary that then gets linked to with different names. Solved the problem for us.

firmware probably needs no stdlib at all,just the language itself,so rust for low level is fine

when stdlib is needed then size becomes a big issue, yes busybox approach helps,but.
