Well, if you had a "built-with-musl" rustup, then you could just use it. But if not, you can curl the s3 bucket and grab them; rustup is ultimately a convenience, not a requirement. I guess that's why I see it as "mostly about rustc", since once you have that, you can compile rustup, and once you can do that, you can get it easily.
Just to be clear: I would like to see better support for all of this, personally. I'm not trying to argue that things are perfect today, just figure out exactly where in the process of getting there all this is, since I use Debian, not Alpine.
