It sure looks excellent, `aft` actually looks very similar to it with the same relay server idea. I don't know the program, but from a first glance, it looks like it requires a relay server. While I don't think it has any major disadvantages, but needing to communicate with an external service might not be reasonable for some people. And many times you might not require a relay server at all such as transferring on a local network, or from a VPS (maybe croc can identify if its on a local network, didn't dig enough into it). Well, you can host yourself a relay server, but it does require a bit more configuration.

Also, some people might like Rust more than Go ;)

Why would this matter for users?

For users, not much since the performance is probably equal between Rust and Go. But for developers it might matter, such as forking the repository, or submitting pull requests and for other reasons they might have.
