I believe RedHat patches this feature out of Grub, at least that was what one of the bugs in RedHat's bugzilla was complaining about (BTW, that bug was posted in this list a couple of days ago, probably in the same thread you started). However, I did not confirm that statement, it might be wrong. Inspecting the grub SRPM and the patches it applies might confirm that. The bug said something about RedHat adding a custom patch to achieve the same effect, the patch would store the "default" and/or "fallback" boot option inside the stage2 file. Though, I did not find any references to that mechanism or any documentation of it. You might have to look into the source and patches to see how that is done... All I can say at this point is "Read the Source, Luke!"
