Description

It's slightly faster according to Zulip, but it's currently missing the equivalent of preserve_order, which we use to dump the config schema.

We could use both, but I'm not sure it's worth the hassle.

Research direction

No file or test is named. Start by locating the existing JSON serialization path used to dump the config schema and compare it with simd-json, focusing on the missing preserve_order equivalent. Done means a measured performance and compatibility decision about whether to adopt simd-json or keep the current implementation.
