Thing is that we have already moved a lot towards the first approach and to be able to move towards the second approach, we must deprecate the API that are designed for the first (existing) approach. Otherwise we'll just be confusing app developers with this contradiction. While I might agree with you that the 2nd approach is better, I don't think its worth it to change towards that now. Since we both disagree about the approach, I'd like to get input from Daniel about this too.
