Eh, why not? Seems like a chicken-and-egg thing. If there's no Rust support for some platform, fewer people will want to write things in it because they won't be able to run them where they want. But the less Rust software there is, the less interest anyone would have in writing build tools for less popular platforms. Break out of these patterns by writing useful software in it that people would like to have on less popular platforms, so more people feel motivated to build and maintain build tools for it.
