Right, but I think when they say "core libraries" they probably mean things like hyper, which are still unstable (though getting closer to stability). That said, a lot of big rust crates have stabilized in the last few months.

yeah, but you still end up needing nightly all the time.

The vast majority of our users are on stable.

It's true that some cases still use nightly, as some people want to opt into cutting-edge stuff. But it's much much less than it was a while back.

I believe you, but at the same time it's an issue every time I go to use it. I want to use this crate, it has a feature flag and now I'm on nightly.

Now, I'm willing to use the bleeding edge, since I'm just just learning the language, but it still just bugs me in that way that code smells always do.

Which crates are you running into, out of curiosity?
