Over the last year of intermittently dossing around with Rust I encountered the need to use nightly regularly, with various crates refusing to compile (and usually I stopped my experimentation there as my barrier to entry was anything harder than pacman -S rust cargo). Yet I did not know until just now that Serde is moving off a dependency on nightly and it is encouraging that this is a trend with similar libraries; I stand corrected.
Serve creator here. The core library 'serde' never actually required nightly. It was just the helper library 'serde_derive' which can automatically implement the serde traits that needed nightly. dtolnay has been doing a wonderful job getting us off nightly. We can't wait to finally get rid of using it.

If you happen to remember which libraries those were, I'd be interested in hearing about them!

Today, that also wouldn't be the case: "rustup update nightly" and "rustup run nightly cargo build" or whatever, with extra stuff to automatically switch per directory.
Rocket just came out; I think it's an extremely interesting library, but https://crates.io/crates/rocket shows that it's been downloaded 618 times. It hasn't exactly taken the world by storm yet. I think it shows great potential though! But it's not a good case of showing that the Rust ecosystem largely depends on nightly.
The article you refer to contained a number of factual errors.
