I think this is still a case-by-case basis. The problem is that we cannot keep track of what methods/classes that Phoenix depends on without Phoenix tells us first. There is a special marker InterfaceAudience.LimitedPrivate(Phoenix) just for that purpose.
For some of the stuff (like SplitTransaction) for example, I do not think that we should have any restrictions in HBase in terms of refactoring. For things like MetaReader, etc I can see that having more stable interfaces there will help both projects.
