I find that it better surfaces the best discussion when there are multiple threads (like in this example), and it keeps showing slightly older threads for longer when there's still discussion happening.
On behalf of everyone else in the world, please invest in headphones.
Broadcasting in this way is boorish and the kind of thing emotionally stunted people do to inflict their will upon others. I'm not saying you're necessarily like that, but you're 'wearing their uniform' so to speak.
Cargo absolutely uses git, or else we wouldn't've had that thing where setting it to use the cli git instead of some reimplementation lead to massive speedups
What I mean is that it doesn’t use git as the source of truth for packages (unless you point at a git repo instead of crates.io). It does use a git repo for the index.
What they meant was probably, that you have the option to rely entirely on using git repositories for your dependencies or even just paths to other projects on your disk.
You can also setup your own dependency registry and only work with that.
