Every time an OTA update is released this same argument ALWAYS ensues. Clearing the Google Framework is a tried and true way to force an update. Yes it's risky, but yes it works. I have cleared the Google Framework to get the last 2 updates on my Nexus 4 as well as my Nexus 10. I have never had an issue.... although some people have. Most issues people had are easily cleared up by removing thier Google account and adding it again.
