Mohammad, There are two sides to using SolrCloud in production - the SolrCloud code, and the Solr 4.0 code that it is a part of.
You can reduce the risk of being caught out by Solr/Lucene 4.0 changes (e.g. index structure changes) by using a Lucene 3.0 index format within Solr 4.0. While there's still risk involved in using an unreleased product, you'll have increased your chances of stability. Still hoping someone has answers to my original questions...
