I would think it unfortunate if this ever happens. Solr in non-cloud mode is simple, easy-to-understand, has few moving parts. Many installations do not need to shard, have real-time-updates, etc. Using the replication handler in "legacy mode" works great for us. The config files are on the filesystem. You need not learn a cli to interact with zookeeper, etc. I would be scared to death running cloud mode in Production if I didn't first obtain an in-depth understanding of zookeeper internals.
I can see if there is a huge burden imposed here and if almost all use-cases require cloud. But as for "api consolidation", there are few api's you need to learn if running non-cloud. So what stops us from focusing apis on the need of cloud installations? And the documentation for non-cloud ought to be simple to maintain, there's so much less to learn and know. For those of you that work as consultants or for support providers, it may seem that everyone is running cloud mode. But my guess is those who run cloud mode are the ones that cannot get by without your services.

The writing on the wall suggests that Solr will eventually (probably 7.0 minimum) eliminate the standalone mode and always operate with zookeeper. A "standalone" node would in fact be a single-node cloud running the embedded zookeeper. Once zk-as-truth becomes a reality, I can see a few advantages to always running in cloud mode. The documentation can include one way to accomplish basic tasks. The CoreAdmin API can be eliminated, and any required functionality fully merged into the Collections API. CloudSolrClient will work for all installations. A script that works for cloud mode will also work for standalone mode, because that's just a smaller cloud. I was planning to open an issue to discuss and implement this. If that's not a good idea, please let me know. None of my main Solr installations are running in cloud mode, so the removal of standalone mode will be an inconvenience for me, but I still think it's the right thing to do in the long term.
