The Hashicorp one came up first in a google search months ago. So, basically no reason.

Etcd will spam your logs on quorum loss. It can easily fill your disk before the node comes back online or you wake up to fix it. Etcd logging is playing with fire. Just be careful.

To defend etcd's implementation though, it is what cockroachdb uses.

IMHO, the code is easier to follow than etcd's.

yes it’s more modular with clear contract between the parts
