Oh, one more minor point, and I know I'm probably in the minority here: 
for most of the cases where I use CentOS, I don't actually care which 
RHEL release it is 'based on.'  I just want 'latest CentOS [567]' for 
95% of my uses.  Well, 5 not as much now, but definitely 6 and 7.  I 
actually don't even have a case in production right now that is strict 
release-number-bound, but I did have a couple at one point.

So I don't care which update the CentOS ISO most closely corresponds 
with; it's CentOS, and the software I need to have work works, since it 
either works with or will soon work with latest RHEL.  (the Dell 
Poweredge stuff, for instance, where I'm 100% fully updated CentOS 6 at 
the moment).  Updates of course get vetted in testing first, but I try 
to not rely on software that is 
update-point-release-strict-number-bound.  And if I were to need that 
kind of strict release number binding, that particular machine would 
probably get Scientific Linux installed, since they do backports of 
certain things to earlier releases and let you stay at a particular 
update level while getting certain other updates. Although there are 
changes in RHEL 7.1 that are challenging things in that respect; see the 
threads on the SL lists related to SL7x and EPEL, for instance.

Of course, you can always trick out a release number bound setup by 
forcing a particular centos-release package to be the one that is 
installed, if it is a 'paper' requirement rather than a real requirement 
(which I have run into before).

But I know others have other requirements; YMMV and all that.  I'm just 
stating what the reality is for my uses at the moment.
