This is the actual truth of the matter. COSMIC is the result of many years of planning and developments in response to customer requests in Pop!_OS. Over time, the COSMIC extensions for GNOME diverged in UX to the point where it was untenable to maintain long-term, and impossible to make further progress without forking. We were going to create a modern desktop environment in Rust from the ground up regardless of whether disputes happened with GNOME Foundation / Core members, even if disagreements helped to accelerate that goal.
Today we have built a highly modular desktop environment in Rust from the ground up that anyone can use as a platform for building an operating system with thanks to the flexibility of the Wayland layer-shell protocol. You may mix and match any arrangement of layer-shell applets in any order. You can even swap out the cosmic session for a different desktop environment’s session, and vice versa load another desktop environment’s session inside of cosmic-comp.
Distribution and user theming is also significantly improved over GTK with programmatic generation of themes—automatically adapting colors at runtime to the most ideal contrasting color values via OKLCH and other related algorithms—which distributions can use to customize to their preferred branding, and app developers can freely adopt without needing to worry about user themes breaking their apps. Users also get the convenience of generating their own custom themes with COSMIC Settings, even if that means creating an abomination of conflicting colors.
We really wanted to improve upon the developer UX for Rust GUIs by creating libcosmic, and have succeeding in doing so with a toolkit based on Iced that uses Elm’s Model-View-Update paradigm. It is so much easier to build apps and applets with libcosmic compared to gtk4-rs. I have a lot of testimonials from developers who have built apps and applets with it. Some of which have also contributed a lot to cosmic and libcosmic, even if they had little or no Rust/programming experience previously.
Also, while it may be alpha, it is very usable. It is only in alpha so long as all features aren’t implemented yet. You may have to supplement a GNOME app here or there. Some bugs are also expected, but it works great otherwise. In many ways better than the 22.04 environment currently offered.

I’ve themed my 22.04 install to death – literally – as one would expect from a first Linux install. I’ve been clicking through multiple GUIs where only the checkboxes, dropdowns and radio buttons showed, zero labels or descriptions. Most recently the Raspberry Pi Imager.
