Thanks: Dan Berrangé XXX UNFINISHED: - Is using uintptr for the handle a good idea? Plugins must return something != 0. In other languages we would allow plugins to return an arbitrary object here, but this is not possible in golang because of lack of GC roots. - Default can_* methods are hard to implement. Ideally we would be able to test if a user plugin implements a
