There are lots of tiny practical annoyances you notice, starting with having to vet dependencies and transitive dependency upgrades extremely carefully. A major one is that dev-dependencies are very broken in a no_std environment. It’s obviously useful to have the std in your build.rs script, but unfortunately, Cargo merges dependencies and devDependencies in a way that’s simply incorrect.

The good news is that every problem I found had an actively discussed GitHub issue and the community is active, so there will be progress.

Yeah, I've run into that, but IIRC this got solved super recently/is being solved. Probably https://github.com/rust-lang/cargo/pull/7820 ?
