Without the intention to undermine anyone's work (and I truly appreciate the work the KeyDB guys did), I would not use this (in production) unless I see Jepsen test results [1] either by Kyle or someone supervised by Kyle. But, unfortunately, databases are complex enough and distributed systems even more, and I've lost many sleepless nights debugging obscure alternatives that claimed to be faster in edge cases. And the worst thing is that these projects get abandoned by the original authors after a few years, leaving me with (to quote a movie) "a big bag of odor".
I see databases as a programming languages - if they have a proven track record of frequent releases and responsive authors after 5-7 years, they are usable for wider adoption.
Then, has someone independently verified the Jepsen testing framework? https://github.com/jepsen-io/jepsen/
