Why can't solo developers or small teams represent solo developers or small teams? If an etcd that has a thin, inflexible API is of value, a small team should be able to fork and manage it (the notion it's smaller and simpler ought to imply it's a lot cheaper to maintain than a multi-API etcd, right?).

If the economics of the situation is "large teams have to maintain tools for small teams and individual users," that doesn't actually scale well, does it?
