+//! # Why move away from serde?
+//!
+//! Serde is a great library, but it has some issues that makes us want to be decoupled from serde:
+//! - The issues documented above with attributes.
+//! - Serde has chosen to not have a MSRV ([source](https://github.com/serde-rs/serde/pull/2257)). We think MSRV is important, bincode 1 still compiles with rust 1.18.
+//! - Before serde we had rustc-serializer. Serde has more than replaced rustc-serializer, but we can imagine a future where serde is replaced by something else.
+//! - We believe that less dependencies is better, and that you should be able to choose your own dependencies. If you disable all features, bincode 2 only has 1 dependency. ([`unty`], a micro crate we manage ourselves)
+//!
+//! **note:** just because we're making serde an optional dependency, it does not mean we're dropping support for serde. Serde will still be fully supported, we're just giving you the option to not use it.
