Why does serde_json specify the preserve_order feature in arrow package

Which part is this question about
library

Describe your question
I want to know why is preseve_order specified in arrow.

arrow-rs/arrow/Cargo.toml

Line 43 in 02371d2

serde_derive = { version = "1.0", default-features = false }

Because this feature turned on, our application using arrow wouldn't work well when getting the output of serialized JSON.
In my local env, all of the tests pass in this repository after removing the feature like this.

// Cargo.toml
serde = "1.0"
serde_derive = "1.0"
serde_json = "1.0"

Additional context

• arrow v18.0.0
• Cargo enables all feature of the dependencies.(we can't exclude features that dependencies have.)
