And I've been running rolling Fedora dev versions for three years, and before that I ran Mandriva Cooker for years. Any geek _can_ keep any given distro rolling on their personal desktop, it's not that difficult to do. Making an OS that you sell to real people for extremely large amounts of money to do mission critical work on across thousands of machines robust enough that you can recommend in-place upgrades for major releases is an _extremely_ different kettle of fish.
We don't _recommend_ upgrades between major versions of RHEL, but you could do it, if you wanted to. It's not like the capability isn't there; it's just packages. We just don't suggest it's the best idea, and doing so has support implications if you have a paid support contract.
