My two-cent opinion.
Disclaimer: I really do not know diddly.
Fedora should release a new ISO called "Fedora Gnome 40" that has only the very latest Gnome stuff. This could include GTK packages not pre-installed in Workstation 34. Maybe even use Rawhide repo ?
and then ship Workstation 34 with Gnome 3.38 stuff, that has been thoroughly tested.
I have not tried the GnomeOS iso by the Gnome project.
