Does this need to be published? I think observable is sufficient.

In case you didn't already know this:

@reflectable (no longer necessary but keeps a symbol around for mirrors).
@observable - (implies @reflectable) a property which we will reference in {{ }}
expressions that we want to auto updated.
@published - (implies @observable) a property settable from html, e.g.:
<class-view retainedBytes="77"></class-view>

True. Thanks for clarifying!

Maybe add a .get to Class:

cls.get('retained');

Done.
