I think you're wrong...
Past give us an idea of Khaled's mind and what sort of thing he will probably add or not, then argv0 is just realistic when he said this or this will probably not be added, he might be wrong, but I'm sure most of the time he is not.
Like Horstl said, he have his way to tell thing and it might be difficult to read/get his post/point but how could you say he "has been discouraging certain feature" ? People ask for something with arguments or not, he is free to reply by saying what he think about the suggestion, it's not his only post that will make a difference.
