pandas has a vendored copy of ujson that has not been kept up to date. ujson itself recommends users should migrate to orjson, it seems to me pandas should as well. While this would mean users need another dependency to utilize JSON, it seems better from a maintenance perspective.

Could we just use pyarrow's json parser?

Is the idea to vendor orjson and adapt it like we have ujson? Or can we just use orjson directly?
