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.
