Hey Marcus, The places I've worked in the past have all used SolrCloud primarily so I can't speak to any specifics, but my impression from reading user-list traffic is that a sizable chunk of Solr's user base prefers "User-Managed" mode (formerly called "standalone"). Some because they don't want to manage a ZooKeeper cluster. Some because the replication model in 'user-managed' fits their needs better. Some I imagine just haven't bothered to update in many years.
I'm absolutely sympathetic to efforts to streamline development and reduce collective debt, but it might be tough to displace such a big chunk of users. I'm curious what others think though. Maybe the proportion of 'user-managed' users out there is smaller than I imagine.
