The fact that Red Hat makes it harder to find individual kernel patches has no effect on the CentOS project itself as CentOS merely rebuilds the source RPMs Red Hat releases.
However, Red Hat also stopped providing RHEL6 test kernels and those kernels have been used and tested, also by CentOS users. So this move by Red Hat does affect Red Hat users and CentOS users alike, isolating them from their community. Most customers wouldn't care, but those that care about these kernel releases have value as well.
Tao Linux, or another community rebuild project, would be an exciting thought though.
