I don't understand what you are trying to say but Anjuta and Glade are respectively
22 and 24 years old.
Anjuta stopped making progress well before GTK 4. GNOME Builder is a great alternative and was developed with GTK 3, the GTK 4 port is coming along quite well thought.
Glade is being phased out for Cambalache by its own maintainer.
I find GNOME development/platform refreshing because it's not hype driven, and it doesn't reinvent itself every year.
In this case I believe it's because System76 want to start designing their own laptop rather than relying on off-the-shelf Clevo designs and some of this keyboard design might make it into their own laptop.
I do like smaller keyboards though, easier to switch with laptop, less finger travel, less travel to the mouse and so on
