Cell Interface has suppport for mvcc. The only thing we'd add to Cell in the near future is support for tags it would seem. Should be easy to add. Should add it now. See backing discussion here: https://issues.apache.org/jira/browse/HBASE-7233?focusedCommentId=13573784&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13573784

Would be good to get these in now.

Marking as 0.96. Can more later.
