So a fancy window manager and a desktop environment (toolkit) in its infancy?
Yes, because when you build a product on top of something, you support your dependencies. Crazy idea, I know.
The foundation is not even one week old, and the first project just got selected as they were already closely working with the Omarchy project on some things.
What makes you come to the conclusion that "more important" dependencies wouldn't receive funding in the future?
Both are cool projects, but their scope is totally different to that of GNOME or KDE.
Limited scope isn't a bad thing.
But both have done great work too - I use gnome-keying and KDE Connect all the time.
