Currently, we have `createRefactoringActions` as the API of the refactoring
engine/library. I think we could introduce a `RefactoringEngine` class that
exposes all user-facing interfaces from the engine, including
creating/accessing actions and providing the mapping of editor command. And the
command registration could be handled inside the class, which I assume would be
simpler. This would also allow us to expose more interfaces in the future via
this class.
(Sorry, I didn't make it to the dev meeting this year... I hope I could get a
chance to meet you in the next dev meeting or the European dev meeting early
next year :)
