What happened to rq (recordquery)?

Record query is such a useful tool, covering JSON, YAML, Protobuf, CBOR, etc, but seems abandoned and depends on the unmaintained v8-rs/v8-sys (and apparently not even building) crate. Were there any forks or alternatives? Or any attempts to revive?

For what its worth, the README explains what happened:

WARNING : rq is in very low maintenance mode while I (dflemstr) focus on other things (such as my day job). Pull requests are welcome but I won't guarantee that I will fix reported issues.
