I feel like every other crate I've run into claims to require nightly.
In reality, they often work perfectly fine on a reasonably-modern stable, and simply haven't updated their documentation and READMEs to indicate "oh yeah, this nightly feature is now in stable, so just use a stable that's newer than version so-and-so".
