I highly doubt "user managed" (aka "standalone") mode will go away completely. It *may* become considered so advanced/expert that we might decide to reduce documentation support around it. But the vast majority of Solr tests that work with a Solr instance do it in this mode or an even lesser mode (EmbeddedSolrServer). It'd be wasteful for such tests to run Solr in the more heavyweight mode just for a lower level unit/integration test. So why kill the ability to run it this way outside of tests.
We've seen some features that only work in SolrCloud mode but that could hypothetically run in standalone mode with a little more effort. Off the top of my head: streaming expressions is one, package manager is another. So if you want such features, you might want to help out in making them work in standalone mode.
