Ok, that was funny, at least to mutt users.
One doesn't find this very often with CentOS. One reason is because they do a great deal of QA before releasing anything, and tell you that if you customize the kernel or use a non-CentOS kernel and break it, you get to keep both pieces.
Also, they're more like a Debian stable--the packages will often be older, but are only released after rigorous testing. Not perfect of course, especially for those like myself who use 3rd party repos, non standard kernels and the like, but as has been said in this thread, it's pretty reliable.
