Nah, it was me not running container versions. The bootstrap keys are used to get daemons up without giving out too much admin access to them, so my guess is that as soon as you have a cluster going, you can always read out or create new bootstrap keys if needed later, but they are not necessary for getting a crashed cluster up, rather to expand or initially create nodes.
