> Have you tried making them small? Rust doesn't optimize programs for size by default, there's a lot of easy ways to shrink binaries (like stripping symbols).

Yeah, I have. I'd come across the guide you linked, any frequently use the subset of those techniques that are available on stable Rust. And I've ended up with simple CLI apps in the 2 to 4 MiB range – which is _fine_ for my use-case, but a bit closer to the size of a Go binary than a C one. (Though, like I said, it's fine for my use case and, if it were important to me, I'm sure I could trim that a bit by picking different dependencies or even dropping to `no_std` in some cases)
