Great replies so far. I'd add that if people want namespacing to actually happen they need to collaborate on an RFC (https://github.com/rust-lang/rfcs/blob/master/0000-template.md https://github.com/rust-lang/rfcs/blob/master/0000-template....). Ideally someone would post a pre-RFC to internals.rust-lang.org so it can be improved before formal submission. Any such RFC needs to take in to account previous discussions (and appreciate that the crates.io team is small). E.g.: https://internals.rust-lang.org/t/crates-io-package-policies/1041 https://internals.rust-lang.org/t/crates-io-package-policies... https://internals.rust-lang.org/t/namespacing-on-crates-io/8571 https://internals.rust-lang.org/t/namespacing-on-crates-io/8... https://internals.rust-lang.org/t/pre-rfc-packages-as-namespaces/8628 https://internals.rust-lang.org/t/pre-rfc-packages-as-namesp...
