If your services are only running on one server with no failover (either
manual or automatic), you are already vulnerable to such downtimes.

I'm not sure it was implied by Thomas that frozen features kernel are a
security issue. But as new vulnerabilities are being discovered, even on a
feature freeze you need to do security updates.

No. But what I understood from what Thomas said is: as you need to reboot
your server anyway from time to time to apply security updates, you may
decide to switch to an even more often updated kernel, if your architecture
permit it (reboot != service interruption).
