It isn't yet integrated with the schema registry, but I think doing so would be a fairly straightforward task. My primary goal before this "Show HN" was 2.6.0 feature completeness.

I'll look into integrating with the schema registry within the next month. Thanks for the reminder!

edit: there's a few other minor kafkacat features that I'd like to implement as well, such as start and end times for consuming, and producing entire files. I think those two, in addition to avro schema registry, are the main features this is missing, but otherwise kcl is much more featureful.

Long term, I think it'd be great to add support for secrets in vault, but I'd like a bit more usage before considering integrating that.
