Yeah, of course erratas change text.There wouldn't be erratas if they 
were no-ops. The point is that they don't change the spirit/intent of 
the text.

Again: what do you think is the existing behavior, and how different 
that is from that described in the proposed errata?

That would be the case if the proposed fix was changing the intent of 
the spec. But it isn't.
