As per discussion in #5875 turned out that we don't have a consistent way to define non-instantiatable classes.

I don't like `final` as it removes flexibility with no visible gain.
I don't like `abstract` since it's not specifically clear what is meant by that. Is this class not complete? Should it be extended?
