Can the newly opened api allows to extend the refactoring (rename/move)

Up until now, there was no way to extend refactorings such as rename/move to pick up custom framework constraints.
This is the case of renaming a field that would understand the naming convention of the bean spec and rename the associated setter and getter.
Similarly, in the JUnitTest plugin, if a method is renamed or a class is moved, the associated test element will be renamed or moved according to the project test organization pattern. Unfortunately it was done through 2 refactorings: first the method/class, second the test method/class. The user has to go through 2 refactorings dialogs and can cancel the second one which would not cancel the first refactoring.

All this preamble to ask this: does the new api allow to add refactoring targets/actions to the list of usages?
