I suppose we ought to have standard guidance to authors on this, but the 
usual process goes something like: warn that the interface is 
deprecated, but maintain it for a release.  Then remove it in a later 
release.  If the changes are such that the new stuff cannot coexist with 
the old you might need to wrap the deprecated code in a macro and 
explain how to get the old interface during the interim...
