Well, in this case we don't necessarily need to break anyone's 
code, it would be possible to stop at deprecation.

But generally speaking, I agree with you, which is why I was 
hoping to move the debate to, "What are the circumstances under 
which these breaks are possible," rather than "Should 
we/shouldn't we".
