Hmm, obsolete knowledge. JFS has supported ACLs and extended attributes for several years now, so in theory you can run SELinux, AppArmor, GrSec or whatever on top of a JFS filesystem. The fact that Fedora doesn't have support for it is an irrelevant piece of trivia (regardless what the Fedora community leaders say or may want you to believe, Fedora *is* still the testing ground of RHEL an that won't change for a long while yet, perhaps Fedora 10). The real fact is that no one has been motivated enough to make sure that SELinux runs on top of JFS. If RedHat sticks to the only ext2/3 filesystems supported mantra is because of two things, First it matches its business model and appeals to its (corporate) customers used to UNIX(R) where there is one and only one filesystem (that varies among vendors) and second, it is justifiable considering the enormous amount of money and human resources it has thrown into that project in the last ten years (who do you think has paid for ext3 and is paying for ext4? The tooth fairy?)
