In theory I agree with you, but generally I'm the one doing the mark-for-translation - and it can get complicated, juggling edits that are OK, but not yet, and edits that are needed now. There is another option - we can put them in, and I can mark them as "don't affect translation" - as far as I know that would mean that they will get picked up later, but I'm not sure about that. Let me ask Nikerabbit (did you know that he's the Translate author?). We'll decide when he has had time to answer.
