It's really a shame that Rust includes the stdlib piecemeal in binary form, debug symbols and all, in every final binary.
I do love Rust but binary sizes have always annoyed me greatly and I always had this nagging feeling that part of all programmers don't take Rust seriously because of it. And I actually have witnessed, several times in the last 2-ish years, older-school programmers berating and ignoring Rust on that basis alone (so the author is quite right to call this out as a factor).
Looking at the https://github.com/johnthagen/min-sized-rust repo, final binary size of 51 KB when compilation / linking / stripping takes stdlib into account (and not just blindly copy-pasting the 4MB binary blob) is acceptable and much more reasonable. I wouldn't care for further micro-optimizations e.g. going to 20KB or even 5KB (further down the README file).
I also don't use nightly in my Rust work so I guess I'll have to wait several more years. :(
