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.
