Namespaces are a good idea on paper, but you still need to secure the non namespaced name when you reach a bit of popularity or someone else will who will push malware there knowing people will often add a crate by the name they think it has and not necessarily the one it has.

Non namespaced crates can be io.cargo.blah and the short name can be deprecated or even changed programatically.
