Sure, I know that super constructor arguments are part of the issue (in 
fact that's the angle I was looking this problem at before I realized it 
also impacted JEP 482).

That said, I'm not sure how common of a pattern this really is. All the 
examples I've seen so far have a certain artificial vibe to them. The 
kind of stuff compiler writers like us might want to write in a test :-)

It would be helpful I think to run some analysis and get some numbers. 
I'll see if I can do that, I think I know where to look.
