These are users who should not be using Fedora. In the Debian world you effectivly have four layers:
Sid - developers only
Testing - Will be the next Stable, experienced users only please
Stable - This is what you should be using on your servers
Ubuntu - This is what you put on your desktop/laptop
In the RH world it is similar:
Rawhide - developers only
Fedora - Will form the basis for the next RHEL and the rebuilds, experienced users only, never put into production lest you get stuck on the upgrade treadmill. The one year shelf life is supposed to be your clue.
RHEL Clones - Experienced admins who don't need support deploy these
RHEL - Everyone else uses this on their servers and Workstations
The RH world doesn't currently have a desktop/laptop solution.
Fedora shipped KDE 4 for two reasons. First it was a .0 release, not a beta. Second because eventually a KDE 4.x release would be shipping in a production release so let the Fedora users hammer it into shape.
