As an operator, having fewer dependencies I have to deploy and worry about is a boon to my productivity.

If you were building a kafka like system in house for private use only, then yes I agree with your sentiment. If you are building something to be used by hundreds or thousands of organizations then the cost benefit tradeoffs shift to where it probably makes sense to pull the consensus logic into the primary application itself.

Note that you still have the same number of fault domains if you read the actual proposal.

It does not simplify the system. It is simply replacing the ZK ensemble w/ its own raft impl.

Same number of JVMs, same operational complexity.

Thanks for pointing that out. Thats what I get for not actually reading the proposal.

As an operator, shouldn't you worry if something battle-tested, that implements extremely critical functions that are tricky to implement correctly, is replaced with something that is unproven?

As someone who enjoys sleeping at night, I wouldn't poke something like that with a stick before it has matured for a few years, and before many brave (?) operators have smoothed out most rough edges by landing on them repeatedly with their faces.

Yeah, don't deploy it when its in beta or its first few releases. At some point it will be stable and safe at which point everyone from then on will benefit.
