That's fair. Maybe I was overthinking that part.

If the users get the benefit of lazy initialization with one new keyword (lazy-final), they will likely use it because programmers love to prematurely optimize and sprinkling "lazy" is easy. The result will be, most <clinits> will empty out, except for the ones doing weird stuff.
