Jason did propose (for|let|if)+, see

This was missed when Dave carried things over to the new wiki 
namespaces. It has been discussed at TC39 meetings.

Asserting significance won't do. Andreas and I have agreed with Jason 
that the desugaring is straightforward in all cases and you haven't 
responded directly to that argument. We have lots of detailing to do for 
ES6, and this is not out of line with other missed or overlooked 
problems in proposals.
