From what I can tell, GNOME OS doesn't just ship latest stable GNOME, but also goes out of its way to try to ship the latest stable Linux-ecosystem concepts too.
Its a lot harder for Fedora since they need to support 43 upgrading to 44, but also 42 to 43 to 44, 41 to 42 to 43 to 44, etc. And in some cases there is enough of a difference in those upgrade paths to cause issues, even with the immutable Silverblue (I know since I got bit by an issue that began ~2+ versions before the issue ended up being triggered!).
"You may have to re-install in the future" gives GNOME OS a massive amount of flexibility right now, when GNOME OS has fully stabilized, plus 10 or 15 years, Fedora Silverblue and GNOME OS will probably be in the same place, but until then, GNOME OS just benefits from starting later.
(Not saying either is better than the other)
