Seems like the GNOME strategy is to prepare the desktop environment for unconventional mobile form factors rather than workstations. Which is bewildering and confusing because I wouldn't think to use something like a Linux distribution on anything but a workstation. Though in my opinion Windows (WSL) and MacOS (UNIX) provide elegant developer experiences and advanced capabilities for workstation machines.
It's hard to say where GNOME fits in these days and if it's still relevant. These sorts of changes are great and I appreciate GNOME's work so I have a balanced perspective. Steam Deck even uses KDE Plasma and not GNOME so I don't know other than Endless Mobile where GNOME has opportunities to deploy this other than as a sort of proof of concept demo.
