that's correct - we actually don't manually write the kafka api, but we codegenerate it: https://github.com/vectorizedio/redpanda/blob/dev/src/v/kafka/protocol/

Transactions should land in the next month or so, which is the only thing really missing today. we have a ton of solo devs typically that come from the Go, Rust, JS & Python seem to like it quite a bit because of what you said.
