If you don't want distributed consensus, don't use a distributed consensus algorithm. Raft/paxos is not the best fit for every problem, but for problems where you NEED to ensure consistency, it is the best tool for the job. And while it could have outage problems theoretically, Google's Chubby lock service, written using paxos, has such high availability in it's global instance, that the SRE's introduce artificial mini outages, just so dependent services don't assume it has a 100% SLA.
