The moment you break backward compatibility, it will be worse. We are 
talking about breaking backward compatibility. So let's just accept it 
as it is, there is a mentality about a major jump. A major jump 
(9.6->10) is *the* perfect time to make world changing, changes.

Whiners always find a reason to whine.

Let's be on two feet here. I am not saying we should jump to using json 
notation for our next release. I am simply stating that any largish 
(even if it is a small patch) changes to expected behavior should be 
done with care. We have a window because no matter how much you yell, I 
yell, Magnus yells, or anybody else yells; the telling story will be, 
"10.0 is a huge jump from 9.6". Most people *WOULD NOT CARE* if we only 
changed one thing. They care that we jumped 4 releases. That type of 
communication implies BIG CHANGES.

Whether you like it or not. Whether I like it or not.

Sincerely,

JD
