That’s it pretty much the only thing of note I’ve encountered. But yes I just mean it may not be a perfect drop in replace in all existing scripts at this time for jq like tools for other formats since they will likely take a lot of care in having the encoder for their designated format working well. qq still has a few bugs to iron out and more testing to do.
Note that gojq also fixes and improves on some things compared to jq, like arbitrary-precision arithmetic (jq only preserves), some semantic and parsing improvement and fixes that will likely happen in jq at some point also, time zone/formatting/parsing fixes, etc
