The only reason we were using serde_json::json![...] was to have something to feed into the ContentHash hasher. We didn't need the JSON itself as anything other than a sequence of bytes.
Rather than spending the time to serialize everything as JSON, just to feed the string representation as a sequence of bytes to the hasher, we now feed the values in directly to the hasher as sequences of bytes, bypassing the JSON serialization entirely.
