Yeah, this is awkward to fix. The only way to get all instances would be to keep (weak) references to all instances of a class or iterating over all objects in gc.get_objects(). Both of which seem less than ideal, although I can vaguely imagine the weakref approach. I'd say we skip this one for now.

I have a brief (late) look at this issue, I'm not sure how to trigger the callbacks of all the instances of a class when a watched Parameter is updated at the class level. @jbednar @philippjfr interested in your opinion and if it's worth spending time on this to get it in Param 2.0.
