I’m curious about SPM vs Cargo - are there basic design decisions that make Cargo better or just particularities of thier current states?

I also wish to ask given that uv from Python learnt from cargo,npm and other things. Can it be possible for SPM to have an alternative similar to how uv got made for python too?

(I am not familiar with swift which is why I am asking this question if there's a really big difference between Swift package manager and cargo in the first place to warrant a uv like thing for swift ecosystem. I think someone recently posted a uv alternative for ruby)
