Then they should focus on actually having a full stack SDK development experience instead of throwing it all away with Gtk 4, like it happened with Glade, Anjuta, and whatever else keeps being redone.
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.
The talk about its roadmap is about two years old, the author was asking for monetary support, and it has an Electron like design using browser rendering for Gtk.
>Given the Foundation doesn’t sell products or services, it can only happen with targeted, planned and transparent programmes, funded by donations. Because of the very open nature of the GNOME Project, the Foundation can’t decide for one direction of the GNOME Project for everyone
If you think working on the SDK is a good direction, then you should join the community and work on it, or donate to someone else who's already working on it.
It wasn't worth my time.
Or you could take another outlook and just accept that the work involved in sustaining any community is ongoing and it never ends, no matter how hard you try.
