Yeah, your points are all valid, and I didn't mean to imply that your critique was wrong so much as illustrate why it might not have seemed like the most urgent concern to address. It points out what might be some weak examples, but it doesn't strike at the 'core' of the motivation for the proposal, IMO.
That's quite the can of worms. 
These two threads from last year dealt with exactly that issue, and they were, as far as I can remember, the most contentious threads of the year.
