Well the thing is that Fedora is the testing platform for RedHat.
Fedora is for the desktop users, it is used to test new features, and what RH finds interesting, they add it to their server oriented distro, Red Hat Linux.
So, the fact that Fedora is not server oriented is by design.
That said, a savvy sysadmin would be picky about the filesystem to use in production anyway and could easily use a non-default filesystem.
