Ask HN: Any interest in shared, managed Consul/Etcd/Zookeeper clusters?

I read today about HasiCorp ofering managed Consul in Azure (https://news.ycombinator.com/item?id=23937941). This got me thinking. Consul, etcd and Zookeeper are a kind of infrastructure services that are generally deployed in a pretty standard way. Because you need at least 3 nodes in a cluster for HA, running your own cluster will be relatively expensive for small services. I was wondering if there is any interest here in a shared, multi-tenant, HA Consul/etcd/Zookeeper cluster? The idea would be that instead of paying to run your own 3-5 nodes in an HA configuration, someone else would do it for you, but multiple tenants would use the same cluster - so you'd only pay something like $10/m instead of several times that.
