That's rather a silly charge to be leveling when your own proposal is
such a horrid kluge as this one. As near as I can tell, you intend
that SELinux will be unable to prohibit SELECT FOR UPDATE because it
cannot tell the difference between that and a foreign key reference.
If that isn't a hack, I don't know what is.
