That would mean that those sysadmins relying on the distro's maintainers
response might have been surprised in a very unpleasant way.

Kali and Ubuntu, AFAIK, too. Currently I mostly use the latter two.

Dreams, those dreams...

I maintain several CentOS 6-based servers. They will finally be replaced
by CentOS 7-based, but it's out of my control to upgrade the
distributions ASAP. Hence, I have to do manual upgrades and monitor
security advisories.

I wonder how many CentOS installations will be hit.
