I still don't think we need CLONE_PPIDOK. I've been convinced that we need PF_PPIDOK, and that flag should be cleared on exec(); but I really don't see the process needs to explicitly allow other portions of itself to become its siblings.
(hmm.. might it be useful to allow a process to be able to CLONE_PPID after it has exec()ed? That's the only time I can think of when PPIDOK makes sense. And that seems a pretty unlikely thing to want.)
