Can you be more specific? Cargo was designed and implemented by domain experts (the folks behind Bundler), and I haven't personally felt any longing for any other ecosystem's package manager.
I think I probably don't understand the Cargo Way yet? Here's a thing that always confuses me -- is there a way to specify a rust version that my project intends to target in my Cargo.toml, or am I stuck with a global rust install?
In the current scenario, where the definition of 'Rust' changes on a daily basis, that's a major pain-point, but once Rust hits 1.0 then all future changes will be backwards-compatible (until version 2.0, in the distant future if ever), so it should be much less of an issue.
