### Describe the bug In `v55.0.0` the PR #21767 added the [`preserve_order` feature](https://github.com/apache/datafusion/blob/2cac713274496ba8ee08e58655e80f0d464f6d48/datafusion/physical-plan/Cargo.toml#L90) to `serde_json` dependency in `datafusion-physical-plan`. This feature replaces `BTreeMap`-backed `serde_json::Value` with an `IndexMap` **globally**. This is a major side-effect for applications embedding `datafusion`: - It can affect performance - It makes REST API return keys in different order - It impacts many tests that may have depended on sorted keys - It affects our cryptography that relies on stable sorted JSON representation. Enabling this feature just doesn't seem like a choice that a library should make as its effects are disruptive and non-local. ### To Reproduce - ### Expected behavior I suspect `preserve_order` is only needed for testing and could be enabled in `dev-dependencies` without affecting applications that link `datafusion`.
