Had some time on a plane the other week to start on some tickets for moving towards cloud mode the default mode. https://issues.apache.org/jira/browse/SOLR-17465 is the parent ticket with subtasks under it.
https://github.com/apache/solr/pull/2728 is to let 9x users know about this change. https://github.com/apache/solr/pull/2730 updates Ref Guide to put SolrCloud first https://github.com/apache/solr/pull/2729 actually swaps the default and introduces --standalone flag to bin/solr start command Would love some eyes on this.
