I disagree: in principle, making services and identities orthogonal is clearly the right thing to do. Having (for example) three different, unlinked identities, any of which can use or not use GMail, G+ or YouTube at the user's discretion, is clearly preferable to having a YouTube account, a G+ account, and a GMail account. If pseudonymous identity A doesn't want to use YouTube, then "don't do that, then". If the user later decides that identity A should post a video to YouTube after all, he/she can just do so. Under the old system, that would require the user to either give away the connection between (say) the G+ account and the YouTube account, or to create a fourth account - a second YouTube account - for identity A to use on YouTube.

The problem is that in practise Google is making a bags of the transition to the new model (or what they're telling jmillikin the new model is) - whether through incompetence, or not caring enough, or because they're duplicitous in claiming that they really want to support multiple (externally-facing) identities per Google user.
