There's at least one open data quality issue for `process_open_sockets` on macOS[1]. It's a few years old however and, if you aren't seeing that casting error, you probably aren't hitting it. But that's a good example of the kind of debt that's been built up over time.

(In terms of general purpose/flexible tooling, I'm not aware of a close replacement for osquery.)
