I like the extra time, and there are lots of ways to make it productive: do the 
little cleanup tasks that are always put off; plan better for the summit 
sessions by preparing proof-of-concept code; fix more bugs; work on stable 
branches. I don’t think it’s necessary to wait until after the summit to start 
any work at all on the next release. We’re certainly not waiting in Oslo.
