I was asking about the kernel team's policy.

I could care less for the policies of "certain environments", they are
NOT likely to be a problem: any remotely sane site with a policy that
enforces a deadline to install security updates (including reboots) will
also have policies on scheduling the required maintenance window for
such updates, *including* what to do when the maintenance window can't
be scheduled to avoid SLA violations.  And that's for environments where
you can't just do staggered updates, taking a set of nodes offline to
update and regression-test, and bring them back to production (or
rollback/abort the update should a regression be detected) without much
(if any) impact to services.
