In this suggestion among these suggesitons[1][2], I was referring to  
UA processing and not document conformance. There's nothing made  
impossible in this at all unless we fail to specify consistent  
behaviors for UAs so that authors can rely on that consistency. I  
think if you take another look at these suggestions, they make  
authoring even very complex tables quite simple.

Take care,
