Just received this note from AWS that they've figured out how to reduce this % to less than 0.1%.

"Since then, the team has been working around the clock to find ways to minimize the impact for those requiring a reboot. We're happy to share that we'll now be able to live-update ‎the vast majority of our older hardware for this Xen Security Advisory. This means that over 99.9% of our total EC2 instances will receive the live-update and avoid a reboot. We can also now assure you that all newly launched instances will land on updated capacity, which means for the less than 0.1% of total EC2 instances that require a reboot, you can proactively re-launch these instances in order to avoid the assigned reboot timing (if you prefer)."
