Paxos itself and not something built on top of Paxos like multi Paxos is in fact super simple compared to raft.

Where it get complicated is trying to build a practical replicated log system using Paxos. Raft just happen to clearly and completely define this use case.

What SDPaxos or EPaxos try to achieve is good performance over WAN. Something that Raft and any Paxos variant that rely on a stable leader are very bad at.

This can’t be easily added to raft because the main reason the raft algorithm is simpler is because it assume a stable leader in every operation except leader election.
