Well paxos way more complex than raft. I'm not saying building on top of raft is easy, I'm saying making a MVP raft implementation is easier than paxos.

One thing I wish raft had - a learner role which act like a follower that can't start an election until it has catch up with the rest of cluster. etcd has it, but I wish it was part of the raft instead, as well as bulk log transfer.

Article pointing out a very common issue that anyone who tried implementing raft runs into:

Letting a follower forward request to leader on client's behalf is not easy to implement correctly, that's why most popular raft based software (hashicorp stack) doesn't do that. Not worth it.
