I don't think so. The fact that Linux is changing underneath us is a
compelling reason for back-patching a change here. Our older branches
still have to be able to run on modern OS versions. I'm also fairly
unclear on what you think a fix would look like if it's not effectively
a change in the default.
(Hint: this *will* be changing, one way or another, in Red Hat's version
of 8.4, since that's what RH is shipping in RHEL6.)
