client-toolkit VS wf-wallpaper

Hello! I would like to hear some suggestion and opinions from Rust community about building Wayland ecosystem in Rust based around Smithay and their Client Toolkit. I'm working with Wayland Compositors for over 2 years now (private projects) and wanted to move ahead from C++ to build modern Desktop Ecosystem and it's components (truly unique, not copies of macOS or Windows styles) like notification daemon, customizable desktop shell or powerful wallpaper daemon for any compositor which implements layershell protocol. Current idea is to create wallpaper daemon which uses WGPU to render shaders, images or gifs with comfort of high perofrmance renderer (still learning wgpu and it's slow process). For UI components I would like to use truly amazing KayakUI create which uses JSX-style syntax for designing widgets. Desktop Shell should provide plugins (most likely applied through WASM) for integrating various creates to get e.g. weather info or compositor integration etc.

Lots of very useful information here. The developer of sctk has been super informative!

Wallpaper daemons are kinda silly IMO, so I built a wallpaper plugin for Wayfire that does everything directly in the compositor. And it does support shadertoy style shaders :)
