Rust makes it quite easy to forgo a large portion of the standard library. rustc and cargo are separate tools, if you don't want cargo's features, you can use rustc as normal.
These paths may not be popular but that doesn't mean they aren't well supported, and depending on your niche, may not even be that unpopular. embedded on things that are small enough you're not running embedded Linux, for example, rarely use the standard library.
